How to shape memory wire

WebFor a robotic gripper arm we are designing for factory floor use on very small components, we propose to use electrically activated Shape Memory Alloy (SMA) wire harnesses for actuation. The device being designed is akin to Pick & Place machines used for circuit assembly, but moves over an aircraft-hanger sized work surface on wheels. WebPassing a voltage through the SMA wire or sheet generates the temperature change needed to produce a shape change. When the voltage is removed, the heat dissipates and the material returns to its original shape. SMA can be used alone as an actuator or incorporated into the matrix of a composite structure.
