下肢用パワーアシストスーツにおけるテンショナーを用いた人工筋収縮力伝達機構の提案

抄録

Lower back pain is a major health concern worldwide. One cause of lower back pain is the burden on the lumbar region caused by the handling of heavy objects. To reduce this burden, the Ministry of Health, Labour and Welfare in Japan has recommended “squat lifting.” However, this technique, which supports a large force on lower limbs, is not very popular. Therefore, we aimed to develop a power assist suit for squat lifting. In this paper, we explain the prototype of gastrocnemius-reinforcing mechanism developed in previous research. Next, we discuss the problems of this prototype. Finally, we propose a contraction force transmission mechanism of artificial muscle using tensioner in wire adjustment mechanism using a tensioner as a solution.
