多機能筋電義手の開発

抄録

This paper explains the development of a myoelectric-controlled multi-functional hand prosthesis at the National Institute of Advanced Industrial Science and Technology (AIST). The myoelectric control of electric-powered prosthetic hand has been researched since the early 1960s. Although some prosthetic hands are already commercially available, most are single-function systems—only capable of performing a single function such as open-close—and are thus of limited usefulness in daily life. Therefore, we developed the multi-functional mechanical hand with almost the same size and weight as those currently available; however it is not limited to an open-close function but is also capable of a wrist flex-extend function.
