Smart materials behave differently depending on the conditions. e.g. temperature.
Shape memory alloys can return to their original shape after being deformed.
Nitinol is a shape memory alloy.
When cool you can bend it and twist it like rubber
However if you bend it too far, it will stay bent.
If you heat it above a certain temperature, it will return to its original shape.
Nitinol is used in glasses frames and dental braces. In the mouth it warms up and tries to return to its original shape, so gently pulls the teeth with it.
