摘要： 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.
