Experimental Investigation of Effect of Change in Contact Area by Deformation of Soft Material Fingertip on Resistible Force

Abstract

In this study, we experimentally investigated the effect of change in contact area by deformation of soft material fingertip on the resistible force. In our previous study, harder fingertips in which small bending deformation occurs produce larger resistible forces. When a tangential force was applied, large bending deformation occurred in the soft fingertip. It is assumed that the change in the contact area by bending deformation affected the resistible force.
