Eventually these advanced prosthetic devices will be expected to touch and be touched by other people. As realistic as they may look the currently available prosthetic hands have physical properties that are still far from the characteristics of human skins because they are much stiffer. In this paper different configurations of synthetic finger phalanges have been investigated for their skin compliance behaviour and have been compared with the phalanges of the human fingers and a phalanx from a commercially available prosthetic hand. Methods Handshake tests were performed to identify which areas on the human hand experience high contact forces. After these areas were determined experiments were done on selected areas using an indenting probe to obtain the force-displacement curves. Finite element simulations were used to compare the force-displacement results of the synthetic finger phalanx designs with that of the experimental results from the human and prosthetic finger phalanges. The simulation models were used to investigate the effects of a varying the internal topology of the finger phalanx and b varying different materials for the internal and external layers.
