Abstract
ER (electro-rheological) gel is one of functional materials, which adhesive force increases when an electric field is impressed. In this study, an ER gel is equipped for the human body directly to realize effective rehabilitation or force display. The property of ER gel is applied to a brake element. However, ER gel is used at a curved form, when it is set up on the human body. The force property of ER gels on the curved surface is not known well. Therefore, we develop an experimental device for pre-study on force display, and measure the adhesive force using the device.
