Energy Harvesting from PZT-5A Integrated Bimorph Cantilever Beam

Abstract

This paper presents a theoretical model for simulating a piezoelectric integrated bimorph cantilever beam which acts like a power harvester. A point mass is attached on the free end of the beam. Acceleration is applied in the base of the beam and that causes transvers vibration of the beam. Electric potential is generated on the beam surface. How much electric energy is generated, was simulated by comsol multiphysics. By changing various dimensions and parameters, how the output power varies, were studied.
