Construction and Simulation of Various Structures of Unimorph Piezoelectric Cantilever for Energy Harvest

Abstract

Piezoelectric devices are globally considered as the alternative potential source for energy. The main focus of this paper is to maximize the output voltage in different shapes of piezoelectric cantilever beam with the same dimensions. In this paper we compare the power output between conventional structure and modified structure (E-shape) and conclude that modified structure has more possibilities in generating maximum power. The prototype E-shaped structure shows maximum deflection than the conventional one. This energy harvester is able to remove the battery problem in various fields like wireless, biomedical and so on. The various structure of cantilever beam is designed by using COMSOL multi-physics 5.1. The obtained results are compared using MATLAB simulation.
