| 1 | Effects of sebum properties on skin friction:investigation using a bench test显示文摘The hydro lipid film is an emulsion of sweat and sebum that covers the surface of the human skin and affects the tribological properties of the human skin.This study investigates the effects of the composition of the sebum on the average coefficient of friction.A range of simplified sebums was developed and the friction behaviour was investigated.Five realistic sebums showed a strong variation in friction results,indicating that interpersonal differences in frictional behaviour might have their origin in differences in sebum composition.A more detailed investigation employing controlled variations of individual ingredients showed that friction is highly sensitive to the amount of squalene in the sebum.The amount of fatty acids in the sebum also showed some effects,whilst the amount of cholesterol does not appear to be relevant for the friction behaviour.The main new outcome from this study is that the composition of sebum has a significant effect on the friction response of skin in ways that are currently not yet fully understood. | Kerlen T.Korbeld Michel Klaassen Rikeen D.Jobanputra Erik Gde Vries Marc A.Masen | 2020 | Biosurface and Biotribology2020，6，2： | 1 |
| 2 | Investigation of Experimental Devices for Finger Active and Passive Tactile Friction Analysis显示文摘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,sliding direction,and angle of orientation between fingers and object surface consciously or unconsciously.This work addressed interlaboratory experimental devices for finger active and passive tactile friction analysis,showing two types of finger movement.In active sliding experiment,the participant slid their finger freely against the object surface,requiring the subject to control the motion conditions themselves.For passive sliding experiments,these motion conditions were adjusted by the device.Several analysis parameters,such as contact force,vibration acceleration signals,vibration magnitude,and fingerprint deformation were recorded simultaneously.Noticeable friction differences were observed when comparing active sliding and passive sliding.For passive sliding,stick-slip behavior occurred when sliding in the distal direction,evidenced by observing the friction force and the related deformation of the fingerprint ridges.The employed devices showed good repeatability and high reliability,which enriched the design of the experimental platform and provided guidance to the standardization research in the field of tactile friction. | Xue Zhou Marc A.Masen Jiliang Mo Xinyu Shi Yaosheng He Zhongmin Jin | 2023 | Chinese Journal of Mechanical Engineering2023，36，2： | 0 |
