Applications of Shape Memory Alloys: A Review

Subas Mishra

Abstract

Shape memory alloys (SMAs) impart a potential application in a wide range in micro- and nano-industrial world. Classic properties such as free recovery or pseudo-elasticity still needed further speciﬁcations in smart materials or micro-actuators applications. Nowadays, a primary goal is achieved that these materials offer a price-competitive advantage compared to other functional materials design. Among all types of functional SMAs, NiTi-based SMA attracted much attention in the rapidly growing field of micro-electro-mechanical-systems (MEMS) and bio-MEMS. This paper points out different products of Ni-Ti based SMAs. This will be illustrated by describing some device-based applications realizing why they are successful than that of other micro-instruments.
