Abstract
In this paper, we propose a concept of inner skeleton power assist systems (i.e., power-assisted artificial joints) for human elbow and knee joint and introduce an example of their actuators. The proposed systems can be expected to be artificial joints for the next generation. An electromagnetic actuator is designed as an example of implantable actuators for the inner skeleton power assist systems for the assist of elbow and knee joint motion (i.e., elbow and knee flexion-extension motion in daily activity and rehabilitation for the physically week persons).
