“…Here, Ti 50 Ni 45 Cu 5 SMA is very sensitive to temperature. Its lifetime is at least 10 5 cycles and above [10,11,12,13]. The shape-memory effect for the alloy will occur via the transformation of the Austensite crystallian structure (at a lower temperature) to Martensite (at a higher temperature) when the alloy is heated [14].…”

“…Moreover, stiffness (E) will be increased and the original shape of the alloy will return during the heating process. Based on Lai's report [9,10], the load shown in Fig. 1 can be expressed by the deflection, where P is the load and E is Young's module.…”

“…The shape of the SMA can be recovered by heating the SMA to a specific temperature even though the SMA has been distorted by using an external force [6,7,8]. Therefore, the SMA bending actuator is appropriate to serve as a dynamic splint in facilitating the finger-recovery process.Lai et al [9,10] assessed the mechanical property of the SMA. They also created a series of SMA finger rehabilitation devices [11,12,13].…”

For the purpose of wrist rehabilitation, a new type of SMA (Shape memory alloy) wrist rehabilitation device is developed. The palm will be actuated/lifted by the SMA’s driving force when the shape memory alloy is heated up. Four wires of the shape memory alloy (SMA-Ti50Ni45Cu5 with 1.0mm in ψ) are bundled and passed through a fixed plastic block. The whole set of the SMA wrist rehabilitation devices can give support to the palm’s bending mechanism. A 500(g) adult palm is presented in the experimental work. In order to actuate/lift the palm at a sufficient rehabilitation angle, an electrical circuit of 10(A) is adopted. Consequently, the issue, here, is to present a new type of SMA wrist splint that is used to provide a specified rehabilitation angle for the wrist.
