Sma shape memory alloy
WebShape memory alloys (SMAs), metals that can alter their original shape in response to stimuli such as temperature, have been around since the early 1930s and used in the biomedical industry since the early 1990s. WebShape memory alloys (SMAs) pose unique functional properties like shape memory effect and superelasticity [ 26 ]. These effects are linked with temperature and/or stress driven a diffusionless martensitic transformation of SMA. Moreover, the high energy density makes SMA highly attractive for microactuation purposes [ 27, 28 ].
