摘　　要：分别综述了超磁致伸缩材料和自传感执行器的发展、特性以及应用状况 ,剖析了自传感执行器的物理基础和关键技术 ,并分析探讨了一种新颖的基于 Joule效应和 Villari效应的自传感超磁致伸缩执行器。The development, properties and applications of giant magnetostrictive material and self-sensing actuator were reviewed. The physical elements and key point of self-sensing actuator were analyzed. A novel self-sensing giant magnetostrictive actuator that could perform both as a sensor and an actuator simultaneously due to its Joule effect and Villari effect was introduced and discussed.
