ABSTRACT:
Disclosed are electrorheological fluids having ceramic particles of high ion conductivity and a nonconducting or dielectric fluid. The high ion conductive particle may be a material having the formula Li.sub.y Si.sub.1-x Al.sub.x O.sub.4, where A is a material comprising at least one selected from the group consisting of Ge, P, and Ti, x ranges from 0 to 1, and y ranges from about 3 to about 4. The liquid phase may include a silicone fluid or mineral oil. In the case of a mineral oil, the oil may also include an amine-terminated polyester to improve stability of the fluid.
