Shape memory alloy (SMA) is one of the classes of smart material with high power to weight ratio, small size, and silent actuation. This has an ability of external actuating and also as a sensing element facilitating the dual functionality in the inhabited system, thereby minimize the weight and number of devices. SMA possesses an ability to remember its parent shape (austenite) and recover to it from its deformed state (martensite) at a characteristic transformation temperature. It has an unparalleled energy and power density and delivers large force and displacement. The work density of SMA is high enough to make it a very vital design factor for control applications. This chapter features the important parameters that are neccesery to be consider for designed to build an efficient control mechanism for an SMA instrumented system. This gives a broad spectrum of basic elements that are to be fixed before the developing stage, and the factors are meant to be necessarily quantified. © 2020 Scrivener Publishing LLC.
