Abstract

There are several tactile receptors in the tissue of human fingers. In this study we calculate in detail the deformation of finger tissue when a finger comes into contact with a rigid plate using a FE (finite element) model to clarify the reason for the precise location of the receptors. The FE model is constructed using measured geometry and material properties. As a result, we found that the strain energy is concentrated at the tactile receptor locations. When a frictional force is applied, the stress/strain is concentrated near the edge of the contact area. By calculating the stress/strain distribution using models with/without epidermal ridges/papillae, we found that the shape of the epidermal ridges/papillae influences the stress/strain distribution near the tactile receptors.
