Abstract (en)
[origin: WO2022184776A1] An aerosol-generating device for generating an aerosol from an aerosol-forming substrate. The aerosol-generating device may comprise a device housing defining a chamber for receiving the aerosol-forming substrate; an airflow channel extending from an air inlet in the device housing and through, or in fluid communication with, the chamber; and a puff sensor assembly comprising a heat transfer element and a temperature sensor in contact with the heat transfer element. A first portion of the airflow channel is at least partially defined by an airflow channel wall and a second portion of the airflow channel is at least partially defined by the heat transfer element, the second portion of the airflow channel being adjacent to the first portion and outside of the chamber. At least one of the thermal conductivity or thermal diffusivity of the heat transfer element is greater than the respective thermal conductivity or thermal diffusivity of the airflow channel wall.
