Effects of Composition and Diameter of PZT Transducers on Energy Harvesting

Abstract

Energy harvesting from wasted energy is a brilliant idea suitable for the world energy crisis. Piezoelectric materials such as Lead Zirconate Titanate (PZT) can be used to transform unused mechanical energy to electrical energy that can be stored and used to power electrical devices. Four types of PZT transducer with three different diameters were investigated in this work. The results indicated that the output voltage significantly varies with chemical composition, dimension and figure of merits (d₃₃·g₃₃) of PZT transducers.
