Design of Piezoelectric Energy Harvesting Structures Based on Proof Mass Analysis-Simulation and Experimental Study

Abstract In this work, two types of piezoelectric structures A and B are designed for harvesting maximum amount of energy from motor vibrations. The analysis is conducted under various load conditions with the placement of two different shapes of proof mass (square and rectangular) on the piezoelectric energy harvester. An experimental study is conducted for harvesting energy from motor vibrations using two piezoelectric structures A and B, in which, structure B with the placement of square-proof mass generates maximum power, which is efficient for powering low-power electronic applications.
