We applied a one of functional materials, ER gel, to flexible film circuits, which can be equipped on winding surfaces. The ER gel sheets were introduced to a suit, thus a virtual reality suit which can display a force directly to a body was developed. When an electric field is applied to the ER gel, the adhesional force on the surface of the ER gel, thereby the sear stress of the surface of the gel increases. At the VR suit, a resistant force to bar the motion of the body is generated. In this research, a quantitative evaluation using an experimental equipment modeled one arm and electromyogram evaluation equipped to human were conducted.
