Abstract

Combining a piezoelectric/magnetostrictive laminated composite with a piezoelectric transformer (see figure) generates a giant magnetoelectric (ME) response. The output ME voltage is amplified by the additional piezoelectric transformer layer. The outstanding advantages of the proposed structure include giant ME voltage output, high efficiency, no power consumption, and short response time.
