This paper presents experiment results of an energy transducer based on the magnetoelectric composites. Various configurations of the layered structure composed of the Terfenol-D or/and the Metglas with the PZT-5H have been investigated. The impact of Metglas on the performance of the transducer is outlined. The high output voltage coefficient and the significant deliverable power of the combination Terfenol-D/Metglas/PZT-5H makes it as an ideal energy transducer candidate for wireless powering of embedded device in biomedical applications.
