Paper Abstract

This paper presents novel magnetic actuator and sensor devices with a magnetostrictive/piezoelectric laminate. Both actuator and sensor are based on the conversion of electric and magnetic energies of piezoelectric and magnetostrictive materials via mechanical coupling, thus the advantages of the piezoelectric material, low power consumption and high speed response, are reflected on both functions. Here, several devices, laminations of Tb-Dy-Fe alloys and PZTs with different geometries or properties integrated into a magnetic circuit, are fabricated and their capabilities of magnetic force controlling and displacement sensing are investigated.
