Abstract

The vibration based piezoelectric energy harvester system is considered as an alternative solution for micro-devices, especially for remote area. This paper presents an optimization approach to determine the optimal cantilever beam of a rectangular shape piezoelectric energy harvester to run the micro devices in which power is unavailable. In this study, PZT-5H material has been utilized. The motivation behind this research is to maximize the power behavior by optimizing the cantilever beam's length, width and thickness. Therefore, the proposed rectangular cantilever beam has been optimized by using modified particle swarm optimization (MPSO) algorithm and designed in COMSOL software. Finally, the optimization results of MPSO are compared with other technique to validate the outcomes. The findings show that the performance of the proposed technique is better than other technique in terms of quality and convergence speed.
