碩士 === 大同大學 === 機械工程學系(所) === 100 === For the purpose of wrist rehabilitation , a new type of SMA(Shape memory alloy)- made wrist rehabilitation device is developed. The palm will be lifted up by the SMA’s driving force when the shape memory alloy is heated up.For wires of the shape memory alloy ( SMA-Ti50Ni45Cu5 with 1.0mm in ψ) are bunch and passed through a plastic fixed block. The whole set of the SMA –made wrist rehabilitation device can give a support to the palm’s bending mechanism. A weight of 500(g) for the adult’s palm is present in the experiment work. In order to lift up the palm with a sufficient rehabilitation angle , an electrical circuit of 10(A) is adopted.Consequently, the issue , here, is to present a new type of the SMA-made wrist splint that is used to provide a specified rehabilitation angle to the wrist.
