其他摘要：This paper describes a prosthetic hand for both complementing the function of the hand and for enhancing the function of the body. Types, structures and the operational principles of traditional prosthetic hands are explained, and then the details of prosthetic hands that are controlled by the user's electromyogram (EMG), which is the principal subject of this paper, are also explained. The EMG prosthetic hand was first developed over half a century ago; however, there have been no major changes in the control strategy of EMG prosthetic hands in their long history. Although the traditional EMG control strategy is optimized for EMG prosthetic hands with single degrees of freedom, these days EMG prosthetic hands with multiple degrees of freedom are becoming available on the market, and as a result, many people have difficulties with controlling them. Our research group has developed a novel intuitive EMG controller for prosthetic hands with multiple degrees of freedom, and the developed EMG controller outlines the possibility for physical expansion. Finally, we outline the change in society based on this technology, and its possible future expansion.
