Shape memory alloys (SMA) are thermally activated smart materials. Due to their ability to change into a previously imprinted actual shape by means of thermal activation, they are suitable as actuators for mechatronical systems. Despite the advantages shape memory alloy actuators provide (lightweight-actuators, lower costs etc.), these elements are seldom integrated by engineers into automotive systems. One reason for this phenomenon is among others the varying dynamic behavior at different ambient temperatures. A methodical approach through the problem definition as well as the presentation of different solutions using adaptive resetting introduces experimental results on the behavior of these actuator systems. The publication presents different solutions as well as long-time experiments compared to conventional SMA actuators at automotive conditions.
