　　Tactile perception plays an important role in our daily life and it is usually associated with mechanical responses within the finger.In this study,based on a nonlinear,viscoelastic,and multilayered finite element model of finger,the distribution of von Mises stress within finger under different working conditions and the influences of fingerprints on the tactile perception of the finger were investigated.The results showed that von Mises stress along the interface between the epidermis layer and dermis layer increased with an increase in load.Von Mises stress decreased with an increase in depth from the contact surface to the inside of the finger.Stress waves decayed through the layers of finger tissue.The maximum von Mises stress was located 3.6 mm from the contact center and 0.2 mm from the central depth.
