概要	The piezoelectric vibratory tactile sensors have been studied for measuring the softness and hardness of an object. In this research, a novel piezoelectric vibratory tactile sensor using a horn type longitudinal bar resonator was investigated. For improving the sensitivity on the vibratory tactile sensor, the shape of the longitudinal bar resonator was calculated using the finite element method. The characteristics of sensitivity on these tactile sensors with modified bar type resonators were experimentally shown. It was clarified that the sensitivity on the tactile sensor was increased by modifying the shape of a bar resonator. Then, in order to reduce the vibration displacement at the supporting point on the tactile sensor, the vibration displacement analyses were performed. The dimensions of the resonator, which were not influenced by supporting, were determined. This horn type longitudinal bar resonator is expected as a novel tactile sensor with high performance.
