ERゲルを適用した力伝達素子における片側電極設計

抄録

Electro-Rheological Gel (ERG) is a functional material which changes its surface frictional property according to applied electric field. The one-sided pattern electrodes is a very useful idea to free sliding or rotating parts from wiring arrangements and contribute to extend the application field for ER materials. Application device of ERG is classified into two main groups; linear motion type and rotating motion type. In order to obtain the high ERG effect in the applications, it is necessary to design the pattern of one-sided electrode in which electric field is efficiently applied to ERG. In this study, equivalent circuit model of one-sided pattern electrodes on condition of using the opposite metal plate is proposed for these types of application. On basis of this proposed model, the one-sided pattern electrodes are designed and the validity of this electrode design method using the proposed model is verified by means of a numerical and experimental analysis. The general-purpose tool for the analysis of electric and magnetic field 'ANSYS 9.0' is used.
