Abstract
Electro-Rheological Gel (ERG) is one of functional materials which change their frictional property by applying electric field. A flat plate placed on the ERG sheet clings to the gel by applying an electric field and ERG produces the shear force to the upper plate. Applying ERG to machine parts has been expected because ERG can change the shear force easily by applying electric field. The one-sided pattern of electrodes, which has been developed for Electro-Rheological Fluid (ERF) devices, is a very useful idea to free sliding or rotating parts from wiring arrangements. In this study, the optimum design of one-sided pattern electrodes for ERG is carried out.
