Piezoelectric Energy Harvesting In Wireless Sensor Networks: A Review

Abstract
Due to advancement of technology, the usage of low power portable devices such as mobile phones, wireless sensors and other wireless devices is highly increased. The major limitation of these devices is their limited life time and use of batteries. Hence there becomes a great requirement of energy source that can harvest power. Piezoelectric materials are considered as best for this purpose due to their very high coupling power for mechanical to electrical conversion and require no external voltage. So PZT (Lead Zirconate titanate) material has great capability for power scavenging because they can be used as sensors as well as actuators and can be used on MEMS (Microelectro mechanical) systems. This paper explains a theoretical analysis and simulation of energy harvesting considering a technique of using PZT.
