Abstract

A two-phase magnetoelectric (ME) parallel sandwich was developed by bonding two longitudinally magnetized Terfenol-D/epoxy pseudo-1-3 magnetostrictive composite plates on two longitudinally polarized PZT/epoxy 2-2 piezoelectric composite plates combined longitudinally as a single plate and with their polarization directions arranged in reverse directions. A significantly large ME voltage sensitivity (MEV) of 3.1 V/Oe was observed at the resonance frequency of 42.8 kHz under a relatively low bias field of 0.8 kOe. This resonance MEVwas ∼35 times larger than its nonresonance values, showing great promise of using the proposed sandwich in ME conversion devices.
