초록

This paper provides a new concept of the controllable micro damper using MR(Magneto Rheological)fluids. The damper is composed of four layers which are fabricated by wet etching. The Process of the fabrication is explained and the change of damping property is experimentally shown. Since the damping force is controllable by the applied magnetic field the vibration can be effectively absorbed.
