Abstract

This paper reports a cylindrical shear-mode magnetoelectric (ME) composite developed based on a Pb(Zr,Ti)O 3 (PZT) tube bonded with an NdFeB permanent magnet for magnetic coupling. The existence of a significant ME effect originating from the superior d 15 electromechanical response of the piezoelectric phase is theoretically predicted and experimentally observed with a voltage coefficient of 28.8 mV/Oe (RMS) outside resonance and a maximum power density of 4.56  μ W (cm 3 ·Oe 2 ) −1 at resonance, which are much higher than previous shear-mode ME composites without bias field in the literature. These suggest broad application prospects of this particular ME composite as magnetic sensors, transducers and energy harvesters.
