Abstract

Recently, piezocomposite generating elements (PCGEs) have been proposed for improving the electricity generation performance of piezoceramic wafers. The residual stress in the PZT layer after curing is one of the main reasons for PCGE's enhanced performance, and the outer epoxy-based composites protect the brittle PZT layer. In this work, we propose a d₃₃-mode PCGE that can be used for energy harvesting. The piezoelectric coefficient d₃₃ of the generating element was used as a measure of the electricity generating performance. We fabricated several PCGEs and conducted energy harvesting experiments to verify the concept of the d₃₃-mode coefficient of generating element.
