Abstract

In this article, the piezoelectric energy harvester of cantilever type with the ability to be angled relative to the vertical direction, and also with rectangular fins attached to the end of the harvester has been investigated. The purpose of this study is to investigate the effect of design parameters such as the angle of inclination of the energy harvester, its distance from the wave source, the depth of the beam and the presence or absence of fins at the end of the beam, on the effective voltage of the energy harvester output. Low efficiency is the most important limitation for the advancement of piezoelectric energy harvesters, and for this reason, it is necessary to use methods based on tests and optimization with the aim of increasing the efficiency of piezoelectric energy harvesters. In order to carry out the experimental study, experiments have been designed using the central composite design (CCD) and experimental model analysis and design parameters have been optimized using the response surface methodology (RSM). Also, the effect of equipping the energy harvester with a fin on the final voltage has been investigated. It was observed that the optimal conditions for both finned and non-finned harvesters occurs when distance ratio of the beam from the wavemaker is minimum and the depth of penetration ratio is maximum.
