In recent years, exchanging the large amount of accurate information is required. Various tactile display has been investigated as the method of informing tactile sensation, which is one of the five senses. Tactile display using surface acoustic wave (SAW) has been studied, and Tele-touch system on tactile sensation during rubbing physical surface has been also proposed. In this system, dummy finger is proposed as tactile sensor where the dynamical vibration of the dummy skin is transformed to electrical signal while the finger is exploring on the physical surface. These dummy fingers were fabricated to simulate human finger as for their structure, form and hardness. However, vibration transmitted to the dummy finger is different in rubbing on physical surface, because each dummy finger has different stiffness and dumping. In this paper, dynamical model of the dummy finger and their different characteristic are studied for establish of Tele-touch system.
