STUDY ON A HIGH PERFORMANCE INSOLE WITH HUMAN COMPATIBILITY

Abstract

In recent years, accidents of bone fracture with elderly people increase because of tendency to fall by a little step in a house. As one of this cause, it is considered that a center of gravity position with foot parts of elderly people is changed. Therefore, in order to solve this problem, we propose a new type of insole with high performance by making use of sponge-core-soft rubber actuator (SCSRA). In this study, we apply the actuator to an insole in order to support walking motion. That is to say, a new type of insole to distinguish the foot motion (Pitch or Roll motion) is proposed. To clear the performance of the insole, we develop a test device that is constructed with rotary actuators and a cylinder. In this paper, the mechanism of the proposed insole is explained and basic performances of the proposed mechanism are clarified through some experimental results.
