Abstract：Based on flexible pressure-sensitive conductive rubber, a flexible tactile sensor with four-electrode symmetrical structure, which has three-dimensional force detection function, is designed. Combined finite element analysis software ANSYS with the Mooney-Rivlin theory of rubber, the strain and stress information of the flexible tactile sensor under the action of vertical force and shear stress is obtained through Finite element analysis. The rationality of the structure of three-dimension force tactile sensor and the mathematical models of calculating three dimension forces was verified by experiment. By using finite element analysis on the materials properties and geometric configuration of force transmission hemisphere, the research indicates that the harder materials and the prolate ellipsoid shape (radius a = l. 5b) can optimize the characteristic of the sensor. It provides the basis for the practical application of the flexible tactile sensor for the detection of three-dimensional force.
