This article is devoted to the study of the magnetoelectric element based on magnetostrictivepiezoelectric laminate for use in energy harvesting devices. Magnetoelectric element works on the magnetoelectric effect which exhibits itself as inducing the electric field across the structure in an applied ac magnetic field and arises as a product property of magnetostriction in magnetic layer and piezoelectricity in piezoelectric layer. Possible applications of energy harvesting devices are in monitoring the human security, wireless sensor networks, telemetry, and others. Obtained results showed that one ME element can be used as an energy source.The layered ME structure based on the PZT plate had dimensions of 40x10x0.38 mm, and double-sided electrodes, which were fabricated from three layers Metglas and corresponded in size PZT plate. It was investigated element with dimensions 40x10x0.5mm, and the composition of the PZT-Metglas. Low frequency magnetoelectric coefficient was 1.24 V/(cm·Oe) at an output current of 2.6 microamp, on the resonant frequency of 41 kHz magnetoelectric coefficient was 1.32 V/(cm·Oe) at an output current 205 microamps.
