Investigation of Experimental Devices for Finger Active and Passive Tactile Friction Analysis

Abstract Complicated tribological behavior occurs when human fingers touch and perceive the surfaces of objects. In this process, people use their exploration style with different conditions, such as contact load, sliding speed, direction, angle orientation between object surface consciously or unconsciously. This work addressed interlaboratory experimental devices for finger active passive tactile friction analysis, showing two types movement. experiment, participant slid freely against surface, requiring subject to control motion conditions themselves. For experiments, these were adjusted by device. Several analysis parameters, force, vibration acceleration signals, magnitude, fingerprint deformation recorded simultaneously. Noticeable differences observed comparing sliding. sliding, stick-slip occurred in distal evidenced observing force related ridges. The employed showed good repeatability high reliability, which enriched design platform provided guidance standardization research field friction.
