    摘要: 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.

    摘要: A method for forming a two-way shape memory surface includes thermomechanically training a shape memory alloy under substantially constant indentation strain. Thermomechanical training includes removeably securing an indenter to a surface of the shape memory alloy in its martensite phase, so that an indent is formed in the surface. The shape memory alloy is then heated to its austenite phase while the indenter is secured thereto. The shape memory alloy is then quenched to its martensite phase while the indenter is secured thereto. After thermomechanical training, the shape memory alloy surface exhibits a first indent depth when in its martensite phase, and a second, different indent depth when in its austenite phase. Also disclosed herein is a method for forming one-way and two-way reversible surface protrusions on shape memory alloys.
