Abstract

This paper proposes a new 3-layer elastic cloth actuation mechanism in assistive suit with adjustable structure, based on a 2-layer non-adjustable structure, to increase assistive force on lower back muscle group and reduce pre-tension when user pulls the rubber belt located on the back to receive higher assistive force. The pretension acted on the user will result in faster body fatigue. An experiment involving the measurement of muscle activities is implemented to evaluate the change in assistive force in lower back comparing to the current model of 2-layer nonadjustable prototype. The experimental results show that the new 3-layer structure successfully increase the assistive force in lower back muscle group.
