Design and optimization of piezoelectric energy harvesting systems for enhanced performance in wireless sensor networks

Abstract

The appetite for seeking sustainable energy solutions has now reached a fever pitch and that is where the focus on new ways to tap into renewable energy sources has come to the forefront. Piezoelectric-based energy harvesting is a promising technology for providing electric power to Wireless Sensor Networks (WSNs) in order to extract relevant environmental information. The goal of this study is to maximize the both the mechanical and electomechanical design of such piezoelectric systems to improve their energy harvertsing1. With the help of MATLAB SIMULINK we do research for system response under different condition to understand electric to mechanical responses in an efficient way to arrest energy efficiency. These factors encompass mechanical stability, impedance matching, and efficient energy storage (as in rechargeable batteries). The results offer a general perspective for advancing piezoelectric energy harvesting technologies, and the proposed strategies serve as guidelines for future device design and optimization.
