Abstract
The present invention embodies a piezo-pyroelectric energy converter and is directed to a method and apparatus for conversion of thermal energy to electrical energy and refrigeration. The present invention utilizes one or more piezo-pyroelectric materials with thermally conductive metal electrodes, which resonate at a high frequency and are in thermal communication with hot and cold heat sinks to create a thermal gradient and heat flow along the metal electrodes and the piezo-pyroelectric material.
