| Summary: | 碩士 === 大同大學 === 機械工程學系(所) === 94 === A new type of “Full finger joint dynamic splint” was proposed in this paper. 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.
