Research on the Application Status of Giant Magnetostrictive Material in Drive Field

Abstract

The concept of giant magnetostrictive material, characteristics and main effects were introduced briefly. The actuators based on GMM’s magnetostrictive effect, sensors based on inverse-magnetostrictive effect and self-sensing actuators based on the coupled effects were reviewed. It proposed that self-sensing actuators and sensor actuators on the basis of coupling relationship of magnetostrictive effect, inverse-magnetostrictive effect and other effects were GMM’s new research direction.
