Abstract

The invention is directed to a piezovoltaic energy harvesting laminate that includes a photovoltaic laminar wafer comprised of a plurality of photovoltaic cells and a dielectric wafer that converts mechanical energy to electrical energy. A boundary laminate interface is disposed between the photovoltaic laminar wafer and the dielectric wafer. The boundary laminate contains a metallization layer electrical terminal for the photovoltaic cells and a conduction layer of the dielectric wafer.
