皮肤的力学性能概述

MECHANICAL PROPERTIES OF SKIN: A REVIEW

鉴于皮肤的力学性能对于临床和日用化妆品的重要性,人们已经对在体和离体皮肤的力学性能进行了长期的研究.本文对皮肤力学的近期发展进行了全面的回顾,总结了在体和离体实验的方法和仪器,概述了皮肤的主要力学性能,包括杨氏模量、泊松比、压缩系数、强度、韧性、初应力和初张力、热膨胀系数、约束力/层离能、摩擦系数,以及这些性能的各向异性,并以表格形式收集了现有文献中的有关数据.最后,讨论了有关皮肤力学的一些特殊领域中的未来研究方向.

Due to the importance in clinical and cosmetic applications, the mechanical properties of skin tissue in vivo and in vitro have been studied extensively. In this paper, we present a comprehensive review on the recent developments of skin mechanics. The methods and apparatus of experiments in vivo and in vitro are summarized. The main mechanical properties and their anisotropy are reviewed, which includes Young＇s modulus, Poisson ratio, compressibility, strength, toughness, initial stress/tension, thermal expansion coefficient, binding force/delamination energy, and skin friction coefficient. Data from the literature are grouped and tabulated. Finally, future research directions in special areas are discussed.
