High Performance of W-Shaped Piezo Electric Energy Harvester for Smart Building Application

Abstract

The power requirement of Smart Building-Wireless Sensor Network (SB-WSN) is achieved using the piezoelectric energy harvester. This article proposes a novel high-performance bimorph W-shaped Piezoelectric Energy Harvester (W-PEH) using different ceramic piezoelectric materials and proof mass material combinations [PZT-5A & Copper, PZT-5H & Copper, PZT-5J & Copper, PZT-5A & Platinum, PZT-5H & Platinum and PZT-5J & Platinum]. Three cases of W-PEH without proof mass, with single proof mass and with split proof mass are developed to improve the output performance. The electrical performance results under open and short circuit conditions are examined. The simulation is performed using COMSOL Multiphysics software.
