摘要

本研究針對腕關節的復健所需，擬開發出一款新型腕關節復健輔具，主要是藉由形狀記憶合金(Shape Memory Alloy , SMA)加熱伸直產生的驅動力來提供腕關節復建時將手掌舉起的助力。本研究採用Ti50Ni45Cu5 形狀記憶合金，將四根線徑ψ1mm 形狀記憶合金組成一束後穿過塑鋼固定塊後，將整組形狀記憶合金安裝於可支撐成人手掌的彎曲支撐機構上，並以成人手掌的重量(500g)進行實驗。通入10A 電流後達到將手掌舉起至復健所需的角度為目標。本研究以形狀記憶合金作為動力，成功開發出一款新型腕關節輔具，可將手掌舉起達到復健需求的角度，達成腕關節復健的目的。

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.
