Suspension-type ERF Valves and the Motion Control Systems

 
Linear METERA

ER fluids change their apparent viscosity according to an applied electric field. First, pressure control valve is proposed and one-link manipulator is driven by the valve. Secondly, using suspension-type ER fluid, METERA (Movable Electrode ERF Actuator) is proposed and fabricated linear-METERA and rotary METERA. In addition, a Fiber -planted ER Valve is proposed and fabricated by Making Use of an Increase in Viscosity of Dielectric Fluids Caused by an Electrode Planted with Hair-like Short Fibers.
