Abstract

In contrast to thermal shape memory alloy actuators, electric SMA drives are mainly based on wire elements. Even if the wire looks far less complex than SMA springs, the development is determined by challenges regarding activation and dynamic aspects. Therefore, this chapter presents a fast-track calculation of electric SMA wire drives as well as an introduction into a numerical simulation of these actuators. This chapter is concluded by a strategic overview of an electric SMA valve with closer discussions on subsystems like connectors for SMA wires.
