The Use of Shape Memory Alloy Wires in Actuators

Abstract:

Our contribution will describe the basic fundamentals of shape memory alloys. Emphasis will be given to specific characteristics for the use of shape memory wires in actuators. The investigation of shape memory wires in actuators includes qualitative and quantitative benchmarking based on measurements at different test beds. To display applicability of shape memory wires for different tasks, the main focus will be on the influence of different bias forces, the determination of performance, and the possibility of position control without position sensors.
