Abstract
A heater assembly for an aerosol generating device includes a flexible heating element; a temperature sensor; and a flexible dielectric backing film with an adhesive on a surface of the flexible dielectric backing film, wherein the temperature sensor and the flexible heating element are supported adjacent to each other on the adhesive on the surface of the flexible backing film. The heater assembly allows for a more precise measurement of the heater temperature to be obtained while simplifying the assembly process.

A heater assembly for an aerosol generating device comprising:
- a flexible heating element;
- a temperature sensor;
- a flexible dielectric backing film with an adhesive on a surface of the flexible dielectric backing film, wherein the temperature sensor and the flexible heating element are supported adjacent to each other on the adhesive on the surface of the flexible dielectric backing film;
- and
- a tubular heating chamber;
- wherein a thin film heater subassembly includes the flexible heating element, the temperature sensor and the flexible dielectric backing film, and
- wherein the thin film heater subassembly is wrapped around a surface of the heating chamber with the temperature sensor held adjacent to the heating chamber.
A heater assembly for an aerosol generating device comprising:
- a flexible heating element;
- a temperature sensor;
- a flexible dielectric backing film with an adhesive on a surface of the flexible dielectric backing film, wherein the temperature sensor and the flexible heating element are supported adjacent to each other on the adhesive on the surface of the flexible dielectric backing film;
- and
- a second flexible dielectric film which opposes the flexible dielectric backing film to at least partially enclose the heating element;
- wherein at least a portion of the temperature sensor is positioned between the flexible dielectric backing film and the second flexible dielectric film,
- wherein the flexible dielectric backing film comprises an edge region which is folded over on itself or over the second flexible dielectric film to at least partially enclose the temperature sensor within the fold.
