概要	Piezoelectric vibratory tactile sensors are used for measuring the softness and hardness of an object. In this paper, the sensitivity of the frequency change of the longitudinal-bar-type tactile sensor is presented. The approximate equation of the frequency change of the tactile sensor in contact with an object was derived using the distributed constant-circuit model. Then, the experimental characteristics of the manufactured tactile sensors were shown by measuring the softness and hardness of the test pieces. The sensitivity was increased when the resonator with higher resonance frequency was used. It was also clarified that the sensitivity was inversely proportional to the mass of the resonator. The obtained results will be useful for designing the piezoelectric vibratory tactile sensor.
