Shape memory alloy (SMA) is a special metal material with unique properties, that is, this material can restore to its original shape through pressure or temperature changes after deformation. The successful development of Ti-Ni SMA in the 1960s, with the continuous deepening of SMA theory and application research, SMAs gradually entered the practical stage. At present, SMAs have been widely used in aerospace, biomedicine, mechanical electronics and other fields. This article briefly reviews the application of SMAs and makes perspective comments on the current problems of SMA research.
