Finite Element Analysis for the Design of a Protective Layer of a Disc Piezoelectric Energy Harvester

In this paper, an energy harvester using piezoelectric is designed and ANSYS simulation results are reported. The energy harvester was made in the form of a disk. The top and bottom surfaces of the piezoelectric disk ceramics were made by combining metal shields. The effectiveness of the protective layer was evaluated by simulating the actual pressure distribution on the piezoelectric when the energy harvester with the protective layer was subjected to pressures of 0.05, 0.1, 0.3, 0.5, and 1 MPa.
