Shape-memory alloy

A shape-memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that "remembers" its original shape and that when deformed returns to its pre-deformed shape when heated. This material is a lightweight, solid-state alternative to conventional actuators such as hydraulic, pneumatic, and motor-based systems.

Making Shape Memory Springs with Nitinol wire

Making Shape Memory Springs. With the possible exception of straight wire, the most popular and useful form of Nitinol shape memory alloy for actuators is helical coil springs. Such springs can be used either in extension (tension) or compression, can provide an impressively large stroke, and may be designed to exert significant forces. The...

Shape memory alloy overview. SMAs are a group of metallic alloys that can return to their original form (shape or size) when subjected to a memorisation process between two transformation phases, which is temperature or magnetic field dependent. This transformation phenomenon is known as the shape memory effect (SME).

How do shape-memory materials work?

This is called the shape-memory effect (or thermal shape-memory effect, since heat energy makes it happen). Some shape-memory alloys remember one shape when they're hot and a different one when they're cold, so if you cool them they spring into one shape and if you heat them they "forget" that shape and flex into a different one.
