Piezoelectric Energy Harvesting for Powering Micro Electromechanical Systems (MEMS)

Abstract

Recent advancements in wireless technology and low power electronics such as micro electrome-chanical systems (MEMS), have created a surge of technical innovations in the eld of energy har-vesting. Piezoelectric materials, which operate on vibrations surrounding the system have becomehighly useful in terms of energy harvesting. Piezoelectricity is the ability to transform mechanicalstrain energy, mostly vibrations, to electrical energy, which can be used to power devices. This paperwill focus on energy harvesting by piezoelectricity and how it can be incorporated into various lowpower devices and explain the ability of piezoelectric materials to function as self-charging devicesthat can continuously supply power to a device and will not require any battery for future processes.
