Abstract
In this paper, a simple model for circular piezoelectric energy harvester is theoretically and experimentally studied. For this reason, vibration behavior of a circular piezoelectric device, which simply called piezoelectric buzzer, is modeled as a changeable cross-section beam. A new quartic polynomial function is introduced to precisely describe the vibratory behavior of the circular piezoelectric device. The obtained electromechanical equations of motion are experimentally validated. As a case study, application of the presented circular piezoelectric device is studied when it is used in a galloping-based energy harvester. Finally, the optimized parameters of the presented energy harvester and vibration suppressor are presented and its efficiency is studied.
