As aged society progressing, these days, the number of elder people who need supports their daily lives are increasing. On the other hand, there aren’t enough number of physical therapists (PT) for the people who need especially a light care. It is reported that approximately 30~40% of the people need TP in their life. To solve this kind of problem, our study group has studied a high performance shoes with IoT technology for improvement of rehabilitation efficiency. The high performance shoes include Sponge Core Silicon Rubber Actuators (SCSRAs) in their insoles. As SCSRAs consists with sponge covered with some sorts of silicon, SCSRA can be used not only for actuators but also pressure sensors. When we use SCSRAs as actuators, we should apply air into them with diaphragm pump. Air make them intumesce so that they can give touching signal to a part of the sole. Otherwise, when we use them as pressure sensors, we measure internal pressure and multiply it by surface area to estimate the external force. In this study we researched and estimated the best composition of silicon for SCSRA as an insole in the term of time responsibility for load to them. Also, since the high performance shoes are heavier than other ordinary shoes, we researched allowable mass of the shoes that the patient could walk smoothly with shoes. We compare the variance to x-axis of the gravity point while they are walking.
