Experimental Developmentation of the Viscoelastic Properties of the Human Fingerpad.

Abstract

Understanding the human tactile system is the motivation for this research. The linear viscoelastic mechanical properties of the human fingerpad describe the stress-strain relationship within the fingerpad for any stimulus geometry and any time history of applied forces or displacements. The stress-strain relationships within the fingerpad tissue govern the stimuli to the mechanoreceptors which are the source of all tactile information to the brain. A device referred to as the tactile stimulator was designed and is presented in this work. The tactile stimulator is a versatile device that can provide a variety of dynamic stimuli to any material and measure the displacement and force responses. The stimuli can vary with time and with indentor shape. The device is currently configured to allow normal or tangentiai displacement- controlled stimuli.
