Effects of hydration on tactile sensation

摘要: The routine tasks of washing usually necessitates the immersion parts body in water, which causes hydration and changes mechanical properties superficial layer skin. To determine how affects tactile sensations, skin-surface temperature glabrous hairy skin was first measured under normal conditions (air), after submersion distilled water alone a surfactant-water solution. In these experiments, measurements were made time to achieve complete recovery levels. uptake found be considerably greater than skin, retention significantly prolonged by surfactant additive. Subsequent experiments on based results preceding studies, in-air hydrated thresholds sensation magnitudes vibratory stimuli roughness textured surfaces. Vibrotactile detection threshol...
