Abstract:
A method for producing a plurality of thin film actuators is disclosed. The method includes depositing a film of a shape memory alloy material onto a polyimide film to form a shape memory alloy construction. The shape memory alloy construction is strained from 2 to 8%. Post processing is conducted on the shape memory alloy construction after the step of imparting a 2 to 8% strain. This post processing can be the deposition of additional layers of the slicing of the actuators. Various shape memory metal actuators are disclosed.
