The term electrorheological (ER) fluid applies generally to any liquid that exhibits a marked change in rheological behavior in an external electric field. The ER fluids are typically colloidal suspensions of micron-sized polarizable particles in low conductivity liquids. A large electric field aligns the particles into chains and columns parallel to the field, thereby increasing the resistance to shear. The ER effect is currently being widely studied for variety of automotive products such as shock absorbers, clutches, and engine mounts. It has potential applications also in other vibration damping devices as they occur, for instance, in buildings and other structures which resist shock (e.g. of earthquake) and in designing quiet submarines.
