Normal and untreated skin over six anatomic regions of ten normal subjects were measured under a controlled environment. The average coefficient of friction for all measurements is 0.46±0.15 (p<0.05).
Web1 apr. 2013 · Human skin exhibits an intricate surface structure and nonlinear (visco-)elastic properties, leading to complex mechanical contact and friction behaviour. Physiological responses such as sweating additionally complicate contact mechanics by interactively changing the interface between the skin and counter-surface. WebAlthough rather homogeneously distributed along the human body, these “electronic” skin sensors present a higher density (by 4 to 5 times) at the fingertips and lips. 21 Such connected networks, susceptible to slight vary among individuals should naturally lead to different thresholds of sensitivity between subjects. In addition, the differences between …
