Metals that respond to stresses and strain applied to them. For example heat returns them to their original shape eg Nitinol
A material that starts as a liquid and when vigorously shaken or stirred turn to a solid.
Inks or pigments that change colour in response to heat and different temperatures.
Absorb light and after the light source is removed continue to glow for a period of time.
Can be heated in hot water and when it reaches 62 degrees can be shaped into almost any form and on cooling it becomes solid.
Has special properties which when a current is passed through it, enables it to emit a glowing light.
Regulates the movement of components in contact to provide the right 'feel' or desirable characteristics.
