Application of shape memory alloy (SMA) as actuator

Abstract

This paper deals w ith actuators based on shape memory alloys. The testing device has been developed for experimental verification of shape memory alloy actuator testing. Static characteristic shows the hysteresis of this material. Also dynamic properties have been explored through the step response characteristic. Application of the material as actuator in engineering system is shown.
