Abstract :
In this paper, the electromagnetic energy harvesting scheme by using a Terfenol-D/PZT/Terfenol-D composite magnetoelectric (ME) transducer and a circuit is presented. In the experiments, the electrodes on the piezoelectric layer are connected by a circuit whose impedance is denoted by Z, which is the load impedance. we have analyzed and observed the load dependence of the ME coefficient and the basic behaviors of the power density. A giant sharp ME coefficient αE a of 24.5 mv/Oe appears at 3.72×105 rad/s under the load impedance Z of 2000Ω.
