Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this study was to investigate the static mechanical properties of the fingertips in order to develop the soft artificial fingertips for the myoelectric prosthetic hand. In this paper, relation between the strain and stress of the skin and tissue were investigated as the mechanical properties. The subjects were four normal men and one normal woman. Subject’s index finger and forearm was fixed. The ventral surface of the index finger was pressed with the plate made of the aluminum by changing the displacement of the plate. Then, force applied to the plate, and pressurizing area that the plate comes in contact with the fingertip was measured. These experiments were executed at the various displacements. The strain-stress relation was calculated from them. It was shown that the stress was increased non-linearly with increasing of the strain. The artificial fingertips based on the obtained properties were developed. These tips were made from urethane resin. It was shown that the strain-stress relation of the artificial fingertip was similar to the mechanical properties of the human fingertips. Finally, in order to investigate usefulness of the developed artificial finger, we executed myoelectric control experiments by using the prosthetic hand.
