An inductive heating device (1) for heating an aerosol-forming substrate (20) comprising a susceptor (21) comprises: a device housing (10) a DC power source (11) for providing a DC supply voltage (V.sub.DC) and a DC current (I.sub.DC) a power supply electronics (13) comprising a DC/AC converter (132), the DC/AC converter (132) comprising an LC load network (1323) comprising a series connection of a capacitor (C2) and an inductor (L2) having an ohmic resistance (R.sub.Coil), a cavity (14) in the device housing (10) for accommodating a portion of the aerosol-forming substrate (20) to inductively couple the inductor (L2) of the LC load network (1323) to the susceptor (21). The power supply electronics (13) further comprises a microcontroller (131) to determine from the DC supply voltage (V.sub.DC) and the DC current (I.sub.DC) an apparent ohmic resistance (R.sub.a), and from the apparent ohmic resistance (R.sub.a) the temperature (T) of the susceptor (21).

The present invention relates to a heater assembly for an aerosol generating device. The heater assembly includes a tubular heating chamber and a flexible thin film heater comprising a heating element track supported on a surface of a flexible electrically insulating backing film; wherein the flexible thin film heater is wrapped around an outer surface of the heating chamber with the backing film toward the heating chamber. The invention further includes a temperature sensor comprising a temperature sensing element configured to sense a local temperature, wherein the temperature sensing element is positioned so as to overlap with a portion of heating element track. Because the temperature sensing element overlaps with a portion of the heating element track, the temperature sensor provides a more accurate reading of the temperature of the heating element itself.

A device for emanating materials in the environment, preferably by heat evaporation, including: a supply for materials; an emitter of materials, for emitting the materials from the supply to surrounding environment, by application of power from a power supply according to an operation mode; an operation mode adjusting mechanism for adjusting the operation mode of the emitter, by controlling the power delivered to the emitter according to a determined transfer function. The transfer function is modular, so that it can be changed or completely replaced while keeping at least partially the adjusting mechanism in the device.

A heating element for an aerosol-generating system is provided, the heating element including: a plurality of first filaments; and a plurality of second filaments, in which the plurality of first filaments are configured to heat a liquid aerosol-forming substrate, the plurality of second filaments are configured to convey the liquid aerosol-forming substrate to wet at least a portion of the heating element with the liquid aerosol-forming substrate, and the heating element is arranged to form a mesh, the plurality of first filaments being arranged in a first direction and the plurality of second filaments being arranged in a second direction, and the second direction being transverse to the first direction. A heater assembly, a cartridge, and a method of manufacturing a heating element, are also provided.
