For the fields of robot's sensing, developing artificial arm and leg, and investigating surface property, the sensor that is applicable to response for shear force as well as normal force should be developed. Our developed haptic sensor by combining metal particles in balloon natural rubber has high quality of sensing at 0.01 N ordered force and has the ability of responding at the case of rubbing any bodies. The rubber involves MCF as one of intelligent fluids, and therefore is called MCF rubber. Because of making the rubber more sensitive to the shear force, the fingerprint is also shaped on its surface. The sensing of the MCF rubber is more responsive at the rubbing on a sandpaper than the commercial feeling pressure conductive rubber. The MCF rubber has correlation between the electric current flowing inner the MCF rubber and the surface roughness of the rubbed body.
