Shape Memory Alloys

GM has developed alloys and polymers that change their shape, dimensions, strength, transparency, or stiffness in response to stimuli like heat, stress, magnetic field, or electrical voltage. When the stimulus is removed, they return to their original shape. Devices made of such "shape memory alloys" will sense their environment and respond automatically-and they'll weigh a lot less than what they replace, making cars both smarter and more efficient.

For more information on shape memory alloys visit its wikipedia page.
