Piezoelectric Devices for Power Harvesting on Mechanical Displacements

Abstract:

The paper presents the ability of the piezoelectric devices to capture the environmental vibrations, in order to generate electric power for supplying electronic small portable devices. Theoretical and experimental investigations were performed, both for stack and cantilever beam configuration of the piezoelectric devices, with good agreement between results. An improved mechanical architecture is proposed.
