In this study, we have developed a biomimetic knee joint (BKJ) for assisting human standing motion. In the previous study, we developed an active-type BKJ with artificial pneumatic actuator. However, its weight and size are not suitable for daily use. Thus, in this article, we proposed a passive-type BKJ. We also proposed a shear-force sensitive sheet (SSS) to evaluate unnecessary friction between human and machine in shear direction. We conducted an experiment to evaluate the SSS with testing apparatus which fabricated in order to explore the optimal shapes and materials for the SSS. We performed images processing with images obtained from experiment. It was done to calculate five values which are area ratio, line length, 99% line length, average gradation of line, average radius. We performed multiple regression analysis based on those values and created a model formula.
