Abstract

Energy harvesting or energy scavenging is the process of extracting small amount of energy from the ambient environment through various sources. The available energy for harvesting is mainly provided by ambient light, ambient radio frequency, thermal sources, and mechanical sources. Among available m otion based harvesting techniques, piezoelectric transduction offers high power densities in comparison to electrostatic transduction. Among all suitable piezoelectric materials, the most popular is Pb(Zr,Ti)O 3 (PZT), which is being used extensively in a v ariety of microelectromechanical systems (MEMS) in thin film form. However, PZTbased piezoelectric materials contain lead which is not ecofriendly. The goal of this project, therefore, is to develop novel, eco - friendly lead - free piezoelectric materials wit h piezoelectric properties comparable to those of PZT.
