    [0001] The present invention relates to an electrically heated smoking system that includes a heater to heat an aerosol-forming substrate.
    [0002] US-A-5 353 813 describes a tubular arrangement with blades for use as an external heating element in an electric smoking article. The heating element comprises a number of carbon sheets arranged around a spiral reinforced cardboard reinforcement tube. An electrical connection is formed at one free end of the blades, while a common carbon ring connects to the other end of the carbon blades to form a common electrical connection. When the blades are energized, they heat up to provide a heating zone with a temperature in the range of 300 ° C to approximately 900 ° C.
    [0003] The inventors appreciated that it would be advantageous to provide an electrically heated smoking system which was easier to manufacture and also required fewer components in its construction.
    [0004] According to a first aspect of the invention, an electrically heated smoking system is provided to receive an aerosol-forming substrate, the system comprising: at least one heater to heat the substrate to form the aerosol, and a source of power to supply energy to at least one heater, where the at least one heater comprises one or more electrically conductive tracks on an electrically insulating substrate, the one or more electrically conductive tracks having characteristics of resistance temperature coefficient so that the or more electrically conductive tracks can act both as a resistive heater and as a temperature sensor.
    [0005] According to the first aspect of the invention, there is also provided a heater for use in an electrically heated smoking system, the heater comprising one or more electrically conductive tracks on an electrically insulating substrate.
    [0006] According to the first aspect of the invention, the use of a heater in an electrically heated smoking system is also provided, the heater comprising one or more electrically conductive tracks on an electrically insulating substrate, one or more electrically conductive tracks having resistance temperature coefficient characteristics so that one or more electrically conductive tracks can act both as a resistive heater and as a temperature sensor.
    [0007] By using a heater that comprises electrically conductive tracks on an electrically insulating substrate, which can act both as a heater and as a temperature sensor, the number and size of components required in the electrically heated smoking system can be reduced. This allows the size of the electrically heated smoking system to be reduced. In addition, the electrically insulating substrate can be very thin, allowing for an additional size reduction. In addition, some or all of the necessary electronics, wiring and connections can be incorporated into the same electrically insulating substrate as the heater. In addition, the heater can be manufactured more directly and economically than some of the prior art heaters which require each heating element to be individually formed. The heater allows great flexibility in the design: the electrically conductive tracks can be arranged on the electrically insulating substrate as desired and in order to provide the desired heat distribution.
    [0008] Preferably, the electrically heated smoking system further comprises an electronic circuit arranged to control the power supply from the power supply to the at least one heater.
    [0009] Preferably, the power supply supplies energy to at least one heater depending on the temperature detected by one or more electrically conductive tracks and a desired temperature. That is to say, a return is provided which allows the power supply to maintain the heater, and the aerosol forming substrate, at a specific desired temperature. This is achieved without the need for a separate temperature sensor. Preferably, the electrically heated smoking system includes an electronic circuit arranged for this purpose. Preferably, the desired temperature is a temperature at which the heater heats, but does not burn the aerosol-forming substrate.
    [00010] Preferably, the electrically heated smoking system further comprises a thermally insulating material to insulate the at least one heater. The thermally insulating material can insulate the material from the outside of the electrically heated smoking system. Preferably the heater comprises a portion of electrically insulating substrate which has a thermally insulating and / or reflective structure thereon.
    [00011] According to a second aspect of the invention, an electrically heated smoking system is provided to receive an aerosol-forming substrate, the system comprising: at least one heater to heat the substrate to form the aerosol, the at least one heater comprising one or more electrically conductive tracks on an electrically insulating substrate; a power supply to supply power to at least one heater; and a thermally insulating material to insulate the at least one heater.
    [00012] According to the second aspect of the invention, there is also provided a heater for use in an electrically heated smoking system, the heater comprising one or more electrically conductive tracks on an electrically insulating substrate.
    [00013] According to the second aspect of the invention, the use of a thermally insulating material in an electrically heated smoking system that has a heater comprising one or more electrically conductive tracks on an electrically insulating substrate is also provided.
    [00014] The thermally insulating material reduces the heat loss from the heater and also protects a user who uses the electrically heated smoking system from burning. The thermally insulating material is preferably positioned around the aerosol forming substrate in order to provide the greatest thermal insulation. The thermally insulating material must be a material which will not degrade at the high temperatures reached in the electrically heated smoking system. Not all thermally insulating materials will be suitable. Preferably, the thermally insulating material comprises a metal or other non-combustible material. In one example, metal is gold. In another example, the metal is silver. A metal is advantageous as it can reflect heat back into the electrically heated smoking system.
    [00015] Preferably, the thermally insulating material comprises a plurality of air cavities. The air cavities are arranged in a regular pattern. In a preferred embodiment, the air cavities are hexagonal and arranged in a honeycomb structure. The thermally insulating material can be provided on the electrically insulating substrate in addition to the electrically conductive tracks. This allows electrically conductive tracks and thermally insulating material to be manufactured as an element. For some manufacturing methods, electrically conductive tracks and thermally insulating material can be made as part of the same process. Alternatively, the thermally insulating material may be provided in the electrically heated smoking system as a separate element.
    [00016] As in the first aspect of the invention, the electrically insulating substrate can be very thin, allowing for a reduction in size. In addition, some or all of the necessary electronics, wiring and connections can be incorporated into the same electrically insulating substrate as the heater. In addition, the heater can be manufactured more directly and economically than some of the prior art heaters which require each heating element to be individually formed. The heater allows great flexibility in the design: the electrically conductive tracks can be directly arranged on the electrically insulating substrate as desired and in order to provide the desired heat distribution.
    [00017] Preferably, the electrically heated smoking system further comprises an electronic circuit arranged to control the power supply from the power supply to the at least one heater.
    [00018] Preferably, the power supply supplies energy to at least one heater depending on a desired temperature. Preferably, the electrically heated smoking system includes an electronic circuit arranged for this purpose. Preferably, the desired temperature is a temperature at which the heater heats, but does not burn the aerosol-forming substrate.
    [00019] Preferably, the one or more electrically conductive tracks have characteristics of resistance temperature coefficient so that the one or more electrically conductive tracks can act as resistive heaters and as a temperature sensor.
    [00020] In an embodiment of any aspect of the invention, the one or more electrically conductive tracks comprise a plurality of portions, each portion being separately connectable to the power supply. This provides a number of advantages. First, this allows the different portions to be heated for different durations, which can improve the smoking experience, depending on the nature of the aerosol forming substrate. Second, this allows the different portions to be heated to different temperatures, which can also improve the smoking experience, depending on the nature of the aerosol-forming substrate. Third, this allows a specific portion of the heater to be activated at any time. This allows only a portion of the aerosol-forming substrate to be heated at any one time. This can be advantageous since this means that each portion of the aerosol-forming substrate can be heated only once, and not reheated.
    [00021] In an embodiment of any aspect of the invention, the electrically conductive track or tracks comprise a single track of electrically conductive material. A first end of the single track is pluggable on the power supply and a second end of the single track is pluggable on the power supply. In this case, the power supply can also be connectable to one or more central sections of the single track to provide a plurality of portions, each portion being separately connectable to the power supply. In another embodiment of any aspect of the invention, the electrically conductive track or tracks comprise a plurality of electrically conductive material tracks, each track being separately connectable to the power supply.
    [00022] In both aspects of the invention, the electrically conductive tracks are arranged on the electrically insulating substrate in a formation more suitable for heating the aerosol forming substrate. Any number of configurations are possible.
    [00023] In a first embodiment of any aspect of the invention, the electrically insulating substrate is rigid and is arranged to be inserted into the aerosol forming substrate. If the electrically insulating substrate is properly sized and rigid, it can be inserted directly into the aerosol-forming substrate. The electrically insulating substrate can be reinforced in some way to provide sufficient stiffness. In this case, if a thermally insulating material is provided, it can be provided to surround the aerosol-forming substrate.
    [00024] In a second embodiment of any aspect of the invention, the electrically insulating substrate is tubular and the one or more electrically conductive tracks are within the electrically insulating tubular substrate. Such an arrangement can be used as an external heater. The external heater can be used to surround or partially surround the aerosol-forming substrate. In one embodiment, the aerosol-forming substrate is solid and is in the form of a cylindrical plug. In this case, the inner diameter of the outer heater is preferably the same as or slightly larger than the outer diameter of the aerosol forming plug. In the second embodiment, if a thermally insulating material is provided, it can be provided to surround the aerosol-forming substrate and the external heater. The thermally insulating material can be provided on the electrically insulating substrate and the external heater can be formed by wrapping the electrically insulating substrate so that the electrically conductive tracks are towards the inside of the tube and the thermally insulating material is towards the outside of the tube .
    [00025] In a third embodiment of any aspect of the invention, the electrically insulating substrate is tubular and the one or more electrically conductive tracks are on the exterior of the electrically insulating tubular substrate. Such an arrangement can be used as an internal heater. The internal heater can be inserted into the aerosol-forming substrate. In one embodiment, the aerosol-forming substrate is solid and comprises a hollow tube of aerosol-forming substrate. In this case, the outer diameter of the inner heater is preferably the same as or slightly smaller than the inner diameter of the aerosol-forming substrate tube. In this case, if a thermally insulating material is provided, it can be provided to surround the aerosol-forming substrate.
    [00026] In both aspects of the invention, the at least one heater may comprise an end heater for heating the end of the aerosol forming substrate, the end heater comprising one or more electrically conductive tracks on an electrically insulating substrate. In one embodiment, the end heater comprises an electrically conductive spiral track over a circular or substantially circular electrically insulating substrate.
    [00027] In both aspects of the invention, the electrically conductive tracks preferably comprise an electrically resistive material. Most preferably, the electrically conductive tracks are metallic. More preferably, the electrically conductive tracks comprise one or more of: silver, platinum, copper, nickel and palladium. Other materials are possible, for example, electrically "conductive" ceramics (such as, for example, molybdenum disilicide), carbon, graphite, metal alloys and composite materials made of ceramic material and a metallic material. Such composite materials may comprise doped or non-doped ceramics. Examples of suitable folded ceramics include doped silicon carbides. Examples of suitable metals, as well as those listed above, include titanium, zirconium and tantalum. Examples of suitable metal alloys include stainless steel, and alloys containing nickel, cobalt, chromium, aluminum, titanium, zirconium, hafnium, niobium, molybdenum, tantalum, tungsten, tin, gallium, manganese and iron, and nickel-based super alloys , iron, cobalt, stainless steel, Timetal® and alloys based on iron - manganese - aluminum. Timetal® is a registered trademark of Titanium Metals Corporation, 1999 Broadway Suite 4300, Denver, Colorado. In composite materials, the electrically resistive material can optionally be embedded, encapsulated or coated with an insulating material or vice versa, depending on the energy transfer kinetics and the required external physicochemical properties.
    [00028] In both aspects of the invention, the electrically conductive tracks can be coated with a protective layer. Electrically conductive tracks can be coated with one or more of: gold, nickel and glass. The coating of electrically conductive tracks can be advantageous if the electrically conductive tracks comprise a material which will readily oxidize or corrode in some way.
    [00029] In both aspects of the invention, preferably, the electrically insulating substrate comprises one or more of: paper, glass, ceramics, anodized metal, coated metal, and Polyimide. The ceramic can comprise mica, Alumina (Al2O3) or Zircona (ZrO2). Other suitable materials can be used.
    [00030] In a first embodiment of any aspect of the invention, at least one heater is formed: providing the electrically insulating substrate; deposit an electrically conductive paste on the electrically insulating substrate using a template to define a pattern for the electrically conductive paste; and drying the electrically conductive paste to form the electrically conductive tracks.
    [00031] In this first embodiment, the electrically insulating substrate can be any suitable electrically insulating material, but is preferably a ceramic or anodized metal. In this first embodiment, the electrically conductive paste can be any suitable paste, but preferably includes metallic particles. The metal may be silver. The electrically conductive paste can be silver. The electrically conductive paste can also include binders and plasticizers.
    [00032] In a second embodiment of any aspect of the invention, at least one heater is formed: providing the electrically insulating substrate; substantially covering the entire surface of the electrically insulating substrate with an electrically conductive material; protect portions of the electrically conductive material with a mask that defines a standard for the electrically conductive material; and removing the unprotected portions of the electrically conductive material.
    [00033] In this second embodiment, the electrically insulating substrate can be any suitable electrically insulating material, but is preferably polyimide. In this second embodiment, the electrically conductive material can be any suitable material, but preferably includes metal alloys. The metal may be copper. Electrically conductive tracks can be coated with one or more protective layers. In one embodiment, the electrically conductive copper tracks are coated with a first layer of nickel and a second layer of gold.
    [00034] In a third embodiment of any aspect of the invention, at least one heater is formed: providing the electrically insulating substrate; coating the electrically insulating substrate with a metallic film; coating the metallic film with a layer of photoresist material; protect portions of the photoresist material with a mask that defines a standard for the electrically conductive paste; removing the unprotected portions of the photoresist using a light source and chemicals (the exposed photoresist being soluble in a specific solution); remove portions of the metallic film not protected by the photoresist material; and removing the remaining photoresist material to reveal the metallic film in the form of the electrically conductive tracks.
    [00035] In this third embodiment, the electrically insulating substrate can be any suitable electrically insulating material, but is preferably ceramic. Most preferably the substrate is Alumina (Al2O3) or Zircona (ZrO2). In this third embodiment, the metallic film can be any suitable metallic film, but is preferably a platinum film. Electrically conductive tracks can be coated with one or more protective layers. In one embodiment, the electrically conductive tracks are coated with a layer of glass.
    [00036] In both aspects of the invention, the aerosol forming substrate preferably comprises a tobacco containing material containing volatile tobacco flavor compounds which are released from the aerosol forming substrate upon heating. Alternatively, the aerosol forming substrate may comprise a non-tobacco material.
    [00037] In both aspects of the invention, preferably the aerosol forming substrate still comprises an aerosol former. Examples of suitable aerosol builders are glycerin and propylene glycol.
    [00038] In both aspects of the invention, the aerosol-forming substrate is preferably a solid substrate. In a preferred embodiment, the aerosol-forming substrate comprises a tubular substrate that has a cavity for receiving at least one heater. The solid substrate may comprise, for example, one or more of: powder, grains, granules, fragments, spaghetti, strips or leaves that contain one or more of: herbal leaf, tobacco leaf, tobacco streak fragments, reconstituted tobacco , homogenized tobacco, extruded tobacco and expanded tobacco. The solid substrate can be in a loose form, or it can be provided in a suitable container or cartridge. Optionally, the aerosol forming substrate may contain additional volatile tobacco or non-tobacco flavor compounds to be released upon heating of the substrate.
    [00039] In both aspects of the invention, optionally, the aerosol forming substrate can be provided on or embedded in a thermally stable support. In a preferred embodiment, the support is a tubular support that has a thin layer of the solid substrate deposited on its inner surface, or on its outer surface, or on both its inner and outer surfaces. Such tubular support may be formed, for example, from paper, or a material such as paper, a non-woven carbon fiber blanket, a low-mass open-mesh wire mesh, or a perforated metal foil or any other polymer matrix thermally stable. Alternatively, the support can take the form of powder, grains, granules, fragments, spaghetti, strips or leaves.
    [00040] In both aspects of the invention, the aerosol-forming substrate can be deposited on the surface of the support in the form of, for example, a sheet, foam, gel or paste. The solid aerosol forming substrate can be deposited on the entire surface of the support, or alternatively, it can be deposited in a pattern so as to provide a non-uniform flavor supply during use.
    [00041] In both aspects of the invention, alternatively, the support may be a non-woven fabric or a bundle of fibers into which the tobacco components have been incorporated. The non-woven fabric or bundle of fibers may comprise, for example, carbon fibers, natural cellulose fibers, or fibers derived from cellulose.
    [00042] In both aspects of the invention, alternatively, the aerosol-forming substrate may be a liquid substrate, if a liquid aerosol-forming substrate is provided, the electrically heated smoking system preferably comprises a means for retaining the liquid . For example, the liquid aerosol-forming substrate can be retained in a container. Alternatively or in addition, the aerosol-forming substrate can be absorbed into a porous support material. The porous support material can be made of any suitable plug or absorbent body, for example, a foamed metal or a plastic material, polypropylene, terylene, nylon or ceramic fibers. The liquid aerosol forming substrate may be retained in the porous support material prior to using the electrically heated smoking system or alternatively, the liquid aerosol forming substrate material may be released into the porous support material for, or immediately before use. For example, the liquid aerosol forming substrate can be provided in a capsule. The capsule shell preferably melts when heated and releases the liquid aerosol-forming substrate into the porous support material. The capsule can optionally contain a solid in combination with the liquid.
    [00043] If the aerosol-forming substrate is a liquid aerosol-forming substrate, the electrically heated smoking system may further comprise a means for heating a small amount of liquid at a time. The means for heating the small amount of liquid at a time can include, for example, a passage in combination with the liquid substrate. The liquid aerosol-forming substrate is typically forced into the liquid passage by capillary force. The at least one heater is preferably arranged so that during use, only the small amount of liquid aerosol-forming substrate within the liquid passage, and not the liquid within the container, is heated and volatized.
    [00044] Alternatively, or in addition, if the aerosol-forming substrate is a liquid aerosol-forming substrate, the electrically heated smoking system may further comprise an atomizer in contact with the source of the liquid aerosol-forming substrate and which includes at least one heater. In addition to the heater, the atomizer can include one or more electromechanical elements such as piezoelectric elements. In addition or alternatively, the atomizer may also include elements that use electrostatic, electromagnetic or pneumatic effects. The electrically heated smoking system may further comprise a condensation chamber.
    [00045] In both aspects of the invention, the aerosol forming substrate may alternatively be any other type of aerosol forming substrate, for example, the aerosol forming substrate, or any combination of the various types of forming substrate. of aerosol.
    [00046] In both aspects of the invention, during operation, the aerosol-forming substrate may be completely contained within the electrically heated smoking system. In this case, a user can step on an electrically heated smoking nozzle. Alternatively, during operation the aerosol-forming substrate may be partially contained within the electrically heated smoking system. In this case, the aerosol-forming substrate can form part of a separate article and the user can pinch directly on the separate article.
    [00047] In both aspects of the invention, the electrically heated smoking system may further comprise a sensor to detect the air flow indicative of a user giving a pinch. In this mode, preferably, the sensor is connected to the power supply and the system is willing to energize at least one heater when the sensor detects a user by pinching. Alternatively, the system may further comprise a manually operable key for a user to initiate a pinch.
    [00048] In both aspects of the invention, the electrically heated smoking system further comprises a housing for receiving the aerosol forming substrate and designed to be safe by a user. The housing preferably houses at least one heater, the power supply and any other components required for the system, such as the electronic circuit. In one embodiment, the housing comprises a housing and a replaceable nozzle.
    [00049] In both aspects of the invention, in a preferred embodiment, the power supply is a DC voltage source. In one embodiment, the power supply is a lithium-ion battery. Alternatively, the power supply can be a nickel metal hydride battery, a nickel cadmium battery or a lithium phosphate battery.
    [00050] The features described in relation to one aspect of the invention may also be applicable to another aspect of the invention. Specifically, the characteristics and advantages of one or more electrically conductive tracks, which act both as a resistive heater and as a temperature sensor, described in relation to the first aspect of the invention may also be applicable to the second aspect of the invention. The characteristics and advantages of the thermally insulating material described in relation to the second aspect of the invention can also be applicable to the first aspect of the invention.
    [00051] The invention will be further described, as an example only, with reference to the accompanying drawings, in which: figures 1a to 1d show a first embodiment of a method for forming a heater for an electric smoking system; figures 2a to 2e show a second embodiment of a method for forming a heater for an electric smoking system; figures 3a to 3f show a third embodiment of a method for forming a heater for an electric smoking system; figure 4 shows a first embodiment of a heater for use in an electrically heated smoking system; and figures 5a and 5b show a second embodiment of a heater for use in an electrically heated smoking system.
    [00052] As discussed above, the invention provides an electrically heated smoking system that includes a heater. The heater comprises one or more electrically conductive tracks on an electrically insulating substrate. The heater can be formed by a number of different manufacturing processes. Figures 1a to 1d show a first manufacturing process. Figures 2a to 2d show a second manufacturing process. Figures 3a to 3d show a third manufacturing process.
    [00053] Figures 1a to 1d show a manufacturing process that uses a technique similar to that used in screen printing. This manufacturing process can be used with the first or the second aspect of the invention. Referring to figure 1a, an electrically insulating substrate 101 is first provided. The electrically insulating substrate can comprise any suitable electrically insulating material, for example, but not limited to, a ceramic such as MICA, glass or paper. Alternatively, the electrically insulating substrate may comprise an electrical conductor that is isolated from the electrically conductive tracks (produced in figure 1b and discussed below), for example, by oxidizing or anodizing its surface or both. An example is anodized aluminum. Alternatively, the electrically insulating substrate may comprise an electrical conductor to which an intermediate coating called a glaze is added. In this case, the glaze has two functions: to electrically isolate the substrate from the electrically conductive tracks, and to reduce the folding of the substrate. The folds that exist in the electrically insulating substrate can lead to cracks in the electrically conductive paste (applied in figure 1b and discussed below) causing defective resistors.
    [00054] Referring to figure 1b, the electrically insulating substrate is securely attached, such as by a vacuum, while a metal paste 105 is coated over the electrically insulating substrate using a cutout 107. Any suitable metal paste can be used, but, in one example, the metallic paste is a silver paste. In a specifically advantageous example, the paste will comprise 20% to 30% of binders and plasticizers and 70% to 80% of metallic particles, typically silver particles. The cutout 107 provides a template for the desired electrically conductive tracks. After the metal paste 105 has been coated on the electrically insulating substrate 101, the electrically insulating substrate and the paste are burned, for example, in a sintering furnace. In a first firing phase between 200 ° C and 400 ° C, the binders and organic solvents are burned. In a second firing phase between 350 ° C and 500 ° C, the metal particles are sintered.
    [00055] Referring to figure 1c, the result is an electrically insulating substrate 101 that has an electrically conductive track or tracks 103 on it. The electrically conductive track or tracks comprise heating resistors and necessary connection supports.
    [00056] Finally, the electrically insulating substrate 101 and the electrically conductive tracks 103 are formed in the appropriate form for use as a heater in an electrically heated smoking system. Referring to figure 1d, the electrically insulating substrate 101 can be rolled into a tubular shape, so that the electrically conductive tracks are inside the electrically insulating substrate (figure 1d (i)). In this case, the tube can act as an external heater for a solid plug of aerosol-forming material. The inner diameter of the tube can be the same as or slightly larger than the diameter of the aerosol-forming plug. Alternatively, the electrically insulating substrate 101 can be rolled into a tubular shape, so that the electrically conductive tracks are on the outside of the electrically insulating substrate (figure 1d (ii)). In this case, the tube can act as an internal heater and can be inserted directly into the aerosol-forming substrate. This can work well when the aerosol forming substrate takes the form of a tube of tobacco material, for example, such as a tobacco blanket. In such a case, the outer diameter of the tube may be the same as or slightly smaller than the inner diameter of the aerosol-forming substrate tube. Alternatively, if the electrically insulating substrate is sufficiently rigid or is reinforced in some way, some or all of the electrically insulating substrate and electrically conductive tracks can be used directly as an internal heater (figure 1d (iii)) by simply inserting the electrically insulating substrate. and electrically conductive trails directly on the aerosol-forming substrate.
    [00057] Figures 2a to 2e show a second manufacturing process for a heater for an electrically heated smoking system. This manufacturing process can be used with the first or second aspects of the invention. This manufacturing process is based on PCB manufacturing technology. Referring to figure 2a, first, an electrically insulating substrate 201 is provided. Again, the electrically insulating substrate can comprise any suitable electrically insulating material. In this example, the electrically insulating substrate 201 comprises the polyimide.
    [00058] Referring to figure 2b, secondly a metallic film 205 is applied over the substantially entire electrically insulating substrate 201. This can be achieved by lamination or a physical vapor deposition (PVD) process, followed by galvanic reinforcement. Any suitable metal can be used, but in one example, the metal foil is copper. Copper has the advantage that it has a high temperature resistance coefficient. This may mean that it is relatively straightforward to use electrically conductive tracks as a temperature sensor as well as a heater. This is further discussed below. Other metals can be used, however, for example, but not limited to, nickel or platinum.
    [00059] After the metallic film 205 has been applied to the electrically insulating substrate, the unwanted areas of the copper are removed with a subtractive method. Referring to figure 2c, typically a mask 207 is used combined with chemical corrosion, which dissolves copper in all areas not protected by the mask. This results in the device shown in figure 2c which comprises the electrically insulating substrate 201 with the electrically conductive areas 209.
    [00060] Referring to figure 2d, the electrically conductive areas 209 can then be coated. Figure 2d shows a single electrically conductive area 209 for simplicity. The coating is advantageous if using copper, as copper oxidizes quickly. It can be difficult to weld the copper to form the necessary connections if an oxide layer has already formed. In this example, the electrically conductive areas 209 are coated with a double layer comprising a first layer 211 of nickel followed by a second layer 213 of gold. The result is an electrically insulating substrate 201 that has an electrically conductive track or tracks 203 on it. The electrically conductive track or tracks comprise heating resistors and the necessary connection supports.
    [00061] Finally, the electrically insulating substrate 201 and the electrically conductive tracks 203 are formed in the appropriate form for use as a heater in an electrically heated smoking system. Referring to figure 2e, the electrically insulating substrate 201 can be rolled into a tubular shape, so that the electrically conductive tracks are inside the electrically insulating substrate (figure 2e (i)). In this case, the tube can act as an external heater for an aerosol-forming substrate. Alternatively, the electrically insulating substrate 201 can be rolled into a tubular shape, so that the electrically conductive tracks are on the outside of the electrically insulating substrate (figure 2e (ii)). In this case, the tube can act as an internal heater and can be inserted directly into the aerosol-forming substrate. Alternatively, if the electrically insulating substrate is sufficiently rigid or is reinforced in some way, some or all of the electrically insulating substrate and electrically conductive tracks can be used as an internal heater (figure 2e (iii)) simply by inserting the electrically insulating substrate and electrically conductive trails directly on the aerosol-forming substrate.
    [00062] Note that the method described with reference to figures 2a to 2e can also be used to form a reflective, thermally insulating additional layer. This will be discussed in detail below.
    [00063] Figures 3a to 3f show a third manufacturing process for a heater for an electrically heated smoking system. This manufacturing process can be used with the first or second aspects of the invention. This manufacturing process is based on a photolithography technique. Referring to figure 3a, first an electrically insulating substrate 301 is provided. Again, the electrically insulating substrate can comprise any suitable electrically insulating material. In this example, the electrically insulating substrate 301 comprises a thick ceramic, for example, but not limited to Alumina (Al2O3) or Zircona (ZrO2).
    [00064] Referring to figure 3b, a structured metallic film 305 is formed on the electrically insulating substrate 301. Any suitable metal can be used, but in this example, the platinum metallic film.
    [00065] Referring to figure 3c, a photoresist layer 307 is then applied over the metallic film 305. The photoresist layer can be applied by any suitable technique, for example, but not limited to, spin coating.
    [00066] Referring to figure 3d, the unwanted areas of the photoresist are removed. This is achieved by using a mask 309 and exposing the photoresist to intense light from a light source 311. A chemical change occurs in the exposed areas of the photoresist, which allows these areas to be subsequently removed by a chemical agent called a developer.
    [00067] Once the photoresist has been removed in unprotected areas, the metallic film 305 is corroded by wet or dry corrosion. This dissolves the metallic film in all areas not protected by the photoresist. Once the metal has corroded, the remaining photoresist is removed by a solvent. This results in the device shown in figure 3e which comprises the electrically insulating substrate 301 with electrically conductive areas 313.
    [00068] Referring to figure 3f, finally the electrically insulating substrate 301 and the electrically conductive areas 313 can optionally be coated with a passivation layer 315 to prevent corrosion or oxidation of the electrically conductive areas. In this example, the passivation layer is a layer of glass. The result is an electrically insulating substrate 301 that has a track or electrically conductive tracks 303 on it. The electrically conductive track or tracks comprise heating resistors and the necessary connection supports.
    [00069] This heater can be mounted on the electrically heated smoking system using a special structure, for example, a metal clamp, or the heater can be an integral part of a monolithic ceramic base seated within the electrically heated smoking system.
    [00070] Figures 4 and 5a and 5b show two alternative embodiments of the heater of the invention.
    [00071] Figure 4 shows a first modality of the heater in use with an aerosol-forming substrate. In figure 4, the heater 400 comprises a flat, rigid, electrically insulating substrate 401 which has over it electrically conductive tracks 403. (The heater can be in the form shown in figure 1d (iii) or in figure 2e (iii)). The electrically conductive tracks are connectable to a power supply (not shown) via 405 connections. The heater 400 can be inserted directly into an aerosol-forming substrate plug, shown schematically in 407. The heater shown in figure 4 can be using either the first or second aspects of the invention. If the electrically conductive tracks have adequate resistance temperature coefficient characteristics, they can act as resistive heaters as well as a temperature sensor. The heater can be combined with a thermally insulating material to thermally insulate at least one heater from the outside of the electrically heated smoking system with which it is used.
    [00072] Figures 5a and 5b show a second mode of the heater. In figures 5a and 5b, the heater comprises an electrically insulating substrate 501. On a first portion 509 of the electrically insulating substrate, there are electrically conductive tracks 503. The electrically conductive tracks 503 are connectable to a power supply (not shown) via connections 505. On a second portion 511 of the electrically insulating substrate 501, a thermally insulating reflective honeycomb structure 507 is formed on the electrically insulating substrate. The heater in figure 5a is designed to be rolled into a tube from left to right, so that the 509 portion of the electrically insulating substrate that has the electrically conductive tracks is inside and the 511 portion of the electrically insulating substrate that has the structure of thermally insulating beehive 507 is outside. Preferably, the thermally insulating material is also highly reflective. The resulting heater is shown schematically in figure 5b. The honeycomb structure can then be used to thermally insulate the heater and is preferably metallic. The heater shown in figure 5b can be used as an external heater, with the thermally insulating reflective hive structure 507 on the outside in order to isolate the heater from the outside of the electrically heated smoking system with which it is used. This reduces heat loss and also protects a user's hand from burns.
    [00073] In figures 5a and 5b, the thermally insulating reflective honeycomb structure is shown as an integral part of the heater. Alternatively, however, the hive structure can be formed separately and used in the electrically heated smoking system as an independent element. For an external heater, the honeycomb structure can be wrapped around the electrically insulating substrate and the electrically conductive tracks. For an internal heater, the honeycomb structure can be provided around the aerosol-forming substrate. In addition, alternative structure arrangements for the thermally insulating material are possible.
    [00074] The heater shown in figures 5a and 5b can also be used in the first aspect of the invention: if the electrically conductive tracks have characteristics of adequate resistance temperature coefficient, they can act as resistive heaters as well as a temperature sensor.
    [00075] As already mentioned, the manufacturing process illustrated in figures 2a to 2e can also be used to create the hive structure 507. In a similar way to figure 2d, individual areas on the electrically insulating substrate can be coated. If the underlying area is then dissolved or removed in another way, the coating will form air cavities providing thermal insulation. In a preferred arrangement, the air cavities are provided in a honeycomb structure, but other arrangements are also provided for. In addition, the greatest thermal insulation is provided when several layers of the thermally insulating structure are used, for example, by wrapping or stacking several layers. Advantageously, the coating may comprise only a single layer of gold. Gold is specifically useful as it will also reflect heat towards the inside of the electrically heated smoking system, further reducing heat loss. Alternatively, the coating may comprise a single layer of another metal, such as silver. Alternatively, the coating may comprise two layers, similar to that shown in figure 2d.
    [00076] Several advantages are provided by the use of a heater that comprises electrically conductive tracks formed on an electrically insulating substrate. The size of components required in the electrically heated smoking system can be reduced. This allows the size of the electrically heated smoking system to be reduced. In addition, the electrically insulating substrate can be very thin allowing for an additional size reduction. In addition, all or part of the necessary electronics, wiring and connections can be incorporated into the same electrically insulating substrate as the heater.
    [00077] In addition, the heater can be manufactured more directly and economically than some prior art heaters which require each heating element to be individually formed. The heater allows great flexibility in the design: the electrically conductive tracks can be directly arranged on the electrically insulating substrate as desired and in order to provide the desired heat distribution.
    [00078] Furthermore, assuming that the material used for the electrically conductive tracks has appropriate resistance temperature coefficient characteristics, the electrically conductive tracks can act both as resistive heaters and as a temperature sensor. This can further reduce the size of the electrically heated smoking system, as no separate temperature sensor is required. This will be described in more detail.
    [00079] The temperature coefficient of resistance is a measure of the change in resistance with a given change in temperature. The general formula is given by: R = R (1 + aT) where R is the resistance, R0 is the resistance at a given temperature (usually 0 ° C), T is the temperature, and α is the temperature coefficient of resistance . The temperature dependence of conductors is substantially linear.
    [00080] In one method, the voltage and current across the electrically conductive track can be measured and the resistance determined. Then, assuming the known of R0 and α (both of which will be known for a given material), the temperature can be determined. That is to say, the electrically conductive track can act as a temperature sensor as well as a resistive heater.
    [00081] The material must have a resistance temperature coefficient, α, reasonably reliable. That is to say, one that does not change considerably over time under certain conditions. In addition, there may be advantages to using a material that has a large value of the resistance temperature coefficient, α, as this will mean that a relatively small change in temperature results in a large change in resistance. Materials that have a high α value include platinum, nickel, and copper.
