Nitinol is a type of metal wire made of nickel and titanium that is also known as “memory wire”, because it can remember its former shape and transition back to it with a temperature change.

When cooled below a set temperature, nitinol's austenite structure transforms to its martensite phase and has a plastic, deformed shape. The nitinol alloy will hold its deformed shape until it is ...

Using heat-activated nitinol metal, researchers have devised a reversible, ... The transition temperature of the NiTi SMA can be tuned to actuate at higher temperatures such as 60°C.
