Electrotactile Stimulation Based on Strain Energy Density of the Fingertip

Abstract. The shape recognition of an object is important for dexterous manipulation by humans. Therefore, we have developed a haptic display that integrates both electrotactile and kinesthetic sensations to present shape information. However, the electrotactile display only presents the contact field between the object and the fingertip. Therefore, we propose a method of electrotactile stimulation using the strain energy density model at the fingertip to generate the tactile sensation of the fingertip deformation. The result of the shape recognition experiment verifies the efficiency of the proposed method.
