An Arbitrarily Distributed Tactile-Sensor Array Based on a Piezoelectric Resonator

Abstract

This paper introduces a new principle and real structure of a nonscaning, fast-response, arbitrarily distributed tactile-sensor array using a piezoelectiric resonator. The piezoelectric sensor has high stability, and the quasi-digital output can be measured easily and precisely. The sensory position can also be measured quickly and precisely. In addition, the tactile sensor array of soft piezoelectric film is adaptive to the sensitive skin of robot.
