Abstract

In the last decennia, many applications of functional materials based on shape memory alloys have been identified, designed, modeled, and tested. Among them, the NiTi shape memory alloys allowed the development of actuator and /or sensor devices for engineering and medical fields based on their shape memory and super elastic characteristics. Applications as actuator/sensor are due to the detection almost instantly of the induced phase transformations. A succinct approach about NiTi as actuator and/or sensor integration in low melting temperature parts/system or devices is the target of the summarized review.
