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 meterial 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.Keywords
