Abstract

Piezoceramics energy harvesters can transform ambient vibration energy into electrical signals and thus they are being explored for their potential to create self-powered devices for a variety of applications. However, currently available harvesters suffer from low-power outputs. This paper presents a concept of a shear mode piezoceramic energy harvester that utilizes favourable material properties to improve output power harvested from ambient mechanical vibrations. A model of this harvester is also presented to predict the power output and other characteristics of the harvester under various environments.
