Abstract
Here, we propose the device platform of energy domain transfer using a magnetoelectric microcantilever. By incorporating Tb0.3Dy0.7Fe1.9 (Terfenol-D) magnetostrictive materials onto a Pb(Zr0.52Ti0.48)O3 (PZT) piezoelectric microcantilever, we demonstrated energy conversion from the magnetic to the electric domain. By measuring the charge signal from a PZT layer under variable dc magnetic field at constant 60 Hz AC magnetic field, we acquired the magnetoelectric coefficient of 24.4 V/cmㆍOe. The proposed magnetoelectric microcantilever enables the generation of a minimum detectable DC magnetic field up to 1 x 10-12 T at off-resonance.
