Design of Energy Harvester using Piezoelectric Material

Abstract: This paper offers an extensive examination of energy harvesting approaches, with a special focus on the utilization of piezoelectric energy harvesting. This method capitalizes on the unique capability of specific materials to produce an electric field when subjected to mechanical forces, a phenomenon termed the direct piezoelectric effect. Piezoelectric transducers are available in various forms and materials, rendering them adaptable for a wide array of applications. In addition to this, the paper delves into the significance of modeling the behavior of piezoelectric materials in both the time and frequency domains to enhance their utility. Additionally, it investigates several circuit configurations designed to optimize the efficiency of energy harvesting from piezoelectric devices.
