Electrorheological (ER) fluids are suspensions of extremely fine non-conducting but electrically active particles (up to 50 micrometres diameter) in an electrically insulating fluid. The apparent viscosity of these fluids changes reversibly by an order of up to 100,000 in response to an electric field. For example, a … See more The change in apparent viscosity is dependent on the applied electric field, i.e. the potential divided by the distance between the plates.
