摘要

From the point of view of the tribology of the touch quality, when one speaks about softness of an object, one very easily associates it his roughness, the friction and the mechanical properties of materials. With regard to the human skin, the stratum corneum (SC), or cornea layer, is the part of skin surface, which is permanently requested during a friction test. In this work, we present a new approach developed in our laboratory, in order to understand the friction mechanisms of the human skin, and to identify the acoustic signatures which can be correlated with the touch quality. The results show that the acoustic emission is correlated the stiffness and roughness of the stratum coreneum. The application to the analysis of ageing, show clearly the increase of acoustic emission during ageing of human skin.
