Paper Abstract

Conventionally, piezoelectric materials are used to harvest the mechanical energy. However, we show that in the environment where both mechanical and magnetic field energy are available magnetoelectric mechanism can provide higher output power. A laminate structure with morphology metglas / PZT / brass / PZT / metglas was designed and tested under the conditions of (i) vibrations only and (ii) vibration and magnetic field together (dual mode). The results for both hard and soft PZT structure demonstrate that dual mode lead to improved output power. These results are quite important for applications such as powering of sensors used in health monitoring of electromagnetic motors.
