Abstract

During manual exploration or manipulation of objects by humans, the mechanical properties of the fingerpads play a dominant role in governing the sensing of tactile information as well as the control of manipulation. To determine the in vivo compressibility of human fingertips, static indentation experiments were performed using a specially designed apparatus. Volume changes of the fingertips were measured at various depths of indentation by a sharp probe. The results show that the fingertip is almost incompressible for a point indentor, with the highest change in volume (about 1%) occurring at the largest depth of indentation (4 mm). This data is being used in the development of reliable mechanistic models of the fingertip to gain a deeper understanding of the biomechanical bases of tactile sense.
