ABSTRACT:
A shape memory alloy (SMA) actuator assembly is provided that includes an SMA component. The SMA component is used to impart motion in an output shaft. Also provided is a return force component that provides a variable, tailored return force to the SMA component. Additionally, a variety of protective mechanisms are disclosed and utilized to prevent damage to the internal workings and components within the SMA actuator assembly as well as provide protection and safety for external workings.
