　　Tactile perception is essential for humans to perceive the world,and it is usually associated with mechanical responses within the finger.In this study,a nonlinear,viscoelastic,and multi-layered finite element model of the finger was developed.The relationship between the mechanical responses within the finger and tactile perception while the finger scanned different textured surface was studied.The results showed that the sensitivity of tactile perception is affected by the peak value of von Mises stress.The peak value of von Mises stress is influenced by the shape of textures.The peak values of the von Mises stress in descending order are corresponded to a triangular texture,circular texture,and rectangular texture.The peak value of von Mises stress is also influenced by the spacing of textures and it decreases with the decreasing spacing texture.
