The lubrication mechanism by means of an electric field was proposed to reduce friction for the biomimetic load bearing with the low elastic modulus bearing surface. The friction of a stainless steel ball sliding on a conductive silicone rubber plate dropped rapidly on application of an electric field. The continuous change in polarity on the surface by the electric field appeared to affect the adsorbed film adjacent to the bearing material, so that friction seemed to be varied. Additive molecule which promotes adhesion between bearing surfaces to a lubrication liquid deteriorated ability to control the friction. It is possible the technique will be used for an active-control bearing, which use no electrorheological fuild.
