    摘要： An aerosol delivery device includes a power source and an aerosol production component that is powerable to produce an aerosol from an aerosol precursor composition. The aerosol delivery device also includes processing circuitry configured to switchably connect the power source to a load that includes the aerosol production component and thereby power the aerosol production component. A piezo sensor is operatively coupled with the power source and the processing circuitry. The piezo sensor is configured to generate an electrical response to a deformation of the power source, and the electrical response is indicative of a characteristic of the deformation. The processing circuitry is configured to control the aerosol delivery device based at least in part on the characteristic of the deformation indicated by the electrical response.
