Abstract

Electric generators are described herein integrating thermoelectric and piezoelectric components. In some embodiments, an electric generator comprises a thermoelectric film having a plurality of lateral p-n junctions across a face of the film, the lateral p-n junctions established at interfaces between p-type regions and n-type regions. A piezoelectric film is coupled to the thermoelectric film and an electrode is coupled to the piezoelectric film.
