Abstract

An investigation of the mechanistic aspects of tactile sense in primates is carried out using simple models of the fingertip. Four models that range in geometry from a semi-infinite medium to a cylindrical finger with a rigid bone, and composed of linear elastic media under plane strain conditions are analyzed using the finite element method. The results show that the model geometry has a significant influence on the spatial distribution of the mechanical signals, and that the elastic medium acts like a low-pass filter in blurring the signals imposed at the surface. In order for the biomechanical calculations to match the neurophysiological data, it is likely that the models will have to take into account the inhomogeneity of the primate fingerpad.
