Electro-rheological Gel (ERG) is developed to overcome two defects of Electro-rheological Fluid (ERF); one is sedimentation of ER particles, the other is that the seal structure is needed to apply ERF to machine elements. The developed ERG is composed of ER particles and silicone gel. The ER particles are sustained by the gel component, and thus will not precipitate out, which suppresses the decrease in ER effect associated with precipitation. The ERG shows the wide range of shear stress variation in response to the applied electric field. This high performance of ERG is originated in a different mechanism from the ERFs. To apply the electric field to the ERG, it is necessary to sandwich the ERG between plane-parallel electrodes. However, it is not convenient for the practical use to wire the both of electrodes for high voltage supply. In this study, the one-sided structured electrodes are proposed in order to simplify the structure of the wiring. The basic characteristics of ERG on one-sided electrodes are evaluated experimentally. The result shows that its electrodes provide almost same performances as the conventional plane-parallel type. The one-sided ERG mechanism is especially useful in the application of ERG device for rotating or sliding parts.
