Abstract (en)
[origin: WO2022028993A1] An aerosol generating article (201) comprising an airflow channel (211) is disclosed. The article (201) includes a substrate (205) for generating an aerosol, wherein the substrate (205) is disposed inside the airflow channel (211) and a valve (101) disposed inside the airflow channel (211), the valve (101) having an open state and a closed state, wherein the valve (101) is configured to restrict air flow through the airflow channel (211) when in the closed state relative to when in the open state. The valve (101) comprises a shape memory alloy (105) arranged such that the valve (101) changes from the closed state to the open state when heated to a transition temperature of the shape memory alloy (105).
