Abstract

An aerosol delivery device includes an aerosol generator for generating an aerosol in the aerosol delivery device with a membrane and a vibrator which is configured to vibrate a fluid and to aerosolise the fluid by the membrane. The aerosol delivery device further includes a fluid reservoir for receiving the fluid to be aerosolised, the fluid reservoir being arranged in fluid communication with the membrane, a controller which is configured to sequentially operate the vibrator at a plurality of different vibration frequencies, a sensor which is configured to detect at least one electrical parameter of the vibrator for each of the plurality of different vibration frequencies, and a detector which is configured to detect the presence of fluid in contact with the membrane and/or in the fluid reservoir on the basis of the dependence of the detected values of the at least one electrical parameter on the vibration frequency.
