SHAPE MEMORY ALLOY (SMA)
 SMA - solid-to-solid phase transformation - recover completely
SMA has two phases:
1. Austenite - high temperature
2. Martensite - low temperature

 SMA wire is heated by applying voltage.
 The SMA wire shrinks & the joint moves to one direction.
 Opposite SMA wire is heated, the finger rotates to the opposite
direction.
