This MuscleWire® demo spring consists of a small shape-memory alloy actuator wire (SMA wire) wound into a coil. The coil allows you to show how SMA wires work--the coil is very bendable at cooler temperatures, but returns to its original shape when it is warmed up. The coil comes with an info card explaining how to use it.
