A hydration-dependent minimum in finger pad friction on rough surfaces

Abstract Finger pad friction is central to object manipulation and tactile perception, and surface roughness is a key parameter for its control. In a systematic investigation of finger pad friction on aluminum surfaces with varying roughness, measurements from 61 participants rev...

Variation in glabrous skin physiology across anatomical locations on the human hand

Abstract Skin physiology varies greatly between anatomical locations, with impact on tactile sensitivity. Research on the variations in morphology and physiology between different anatomical locations of glabrous skin is limited so far. This study investigates the morphology and...
