Energy harvesting using smart materials and, in particular, piezoelectric material has been a very hot subject for several decades. The brittleness and low performance of PZT, which is widely used for energy harvesting applications, were considered a weakness. The concept of piezocomposite electricity generating elements (PCGEs) has been proposed for improving the electricity generation performance and alleviating brittleness of piezoceramic wafers. The residual stress in the PZT layer after curing is one of the main reasons for the PCGE’s enhanced performance and the outer epoxy-based composites protect the brittle PZT layer. We propose a d 33-mode PCGE that can be used for energy harvesting in roads and bridges. The effective piezoelectric coefficient d 33 eff of the electricity generating element was used as a measure of the electricity generating performance. We fabricated several PCGEs and conducted simple dropping tests to verify the concept of the d 33-mode coefficient of the electricity generating element. Moreover, to ensure even distribution of the impact force on the PCGE, we designed and tested an effective load transfer mechanism with a steel block and a rubber pad.
