Abstract

As further studies of active materials, possibilities of developing the self-sensing actuator using the active material are enhanced increasingly. In this paper, for developing self-sensing actuators based on Magnetic shape memory alloy (MSMA), the sensing properties of MSMA actuator are studied. A testing set is developed to measure and analyze relationships among the impact stress, deformation, temperature and magnetization of the MSMA actuator. The experimental results show that the induced voltage is linear with impact stress and movement, and it is feasible to develop MSMA actuator with self-sensing.
