Theory Analysis on Magnetoelectric Voltage Coefficients of the Terfoneol-D/PZT Composite Transducer

Abstract

The magnetoelectric response of magnetostrictive/piezoelectric laminate composites has been investigated. Based on the piezoelectric and piezomagnetic constitutive equations, and motion equation for the composite plate, the magnetoelectric equivalent circuit has been derived, and the magnetoelectric coefficients predicted. Prototype devices of, as an application example, Terfenol-D/PZT composite plates were fabricated, and experimental values for the magnetoelectric voltage coefficient coincided with the predicted ones.
