Experimental method for determining the 2 dimensional mechanical properties of living human skin

Experimental method for determining the 2 dimensional mechanical properties of living human skin

Medical and Biological Engineering and Computing 15(4): 381-390

An experimental method for obtaining the 2-dimensional skin tension/extension-ratio characteristics of living human skin is described. This method incorporates a strain-gauged pretension device used to determine the naturally existing tension and deformation fields in a specific skin area and a suction-cup system that applies a homogeneous, plane strain field to the skin at controlled straining rates. A series of experiments conducted to validate the use of the method for obtaining quantitative measures of the mechanical behavior of skin in vivo is also presented. This method is used to investigate the variation of mechanical properties with such factors as age, sex, hormonal change, UV radiation and various disease states.
