The SMA was used to construct the full finger joint dynamic splint to offer resistance and auxiliary for rehabilitation in need. The structure design and the control method for dynamic splint were investigated in this study. Four SMA wire with Ti50Ni45Cu5 of ψ1.0mm were bound in one and put it into a silica gel tube. Six pieces of such a silica gel tube can be set along the up or down side of fingers. When patients were going to rehabilitate, the suitable electric current was supplied to the SMA and then it can offer resistance and auxiliary in need. Two kinds of dynamic splint were developed here: The first one offers many kinds of operation functions. It can be used not only for any fingers size but also whole finger in hand. It also fit for using on medical treatment and was controlled by a PC. The second one was designed for personal convenient to use at home and was controlled by single chip microcontroller. Both of them have SMA temperature feedback control capability, and can be operated under a setting temperature safely. The output strength of splint can offer maximum 22N resistance or auxiliary in rehabilitation.
