Simple Piezoelectric based MEMS Energy Harvester Design and Simulation

Abstract

In unmanned areas and smart system, the electronics devices are facing power issues as the batteries don’t have capability to power FOR prolong period of time. Considering this challenge, this study suggests that energy harvesting may be accomplished by using a piezoelectric cantilever that is based on MEMS technology. Cantilevers based on MEMS take use of the piezoelectric effect so that kinetic energy may be converted into voltage. Mechanical energy is produced first when the cantilever is allowed to vibrate. Additionally, the mechanical energy, or stress, that is applied to the cantilever is converted into electrical potential by the piezoelectric material that is located at the end of the cantilever that is fixed. Using the COMSOL Multiphysics program, it was discovered that a MEMS-based piezoelectric cantilever structure has greater deflection and creates additional possibilities. This was discovered when the construction was evaluated. Traditional energy harvesters have some competition in the form of piezoelectric cantilevers for energy harvesting, which are based on microelectromechanical systems. These piezoelectric cantilevers generate voltage and are smaller and more cost-effective than traditional energy harvesters.
