Indentometric analysis of <i>in vivo</i> skin and comparison with artificial skin models

Abstract

The indentometric analysis for both in vivo skin and artificial skin models could be interpreted by using the Hertz theory of contact mechanics. The loading and unloading indentometric curves could be used to assess the viscoelasticity of the investigated materials while creep and stress relaxation processes were analyzed quantitatively by the Kelvin-Voigt model with one relaxation time.
