Abstract
A power conversion device includes an enclosure containing one or more drops of a liquid. A capacitive electret transducer is coupled to the enclosure. In response to applied heat at a heating surface, the liquid vaporizes and then condenses on a flexible membrane of the capacitive electret transducer. The flexible membrane is displaced in response to the vaporization-condensation and the capacitive electret transducer generates an output current.
