Skin anisotropy in vivo and initial natural stress effect: a quantitative study using high-frequency static elastography.
BACKGROUND Most studies on skin anisotropy are carried out in an "average" context, e.g. with an extension/compression test on the skin in vivo, the elastic modulus being estimated for the stretchedExpand

A new experimental method for measuring skin's natural tension
Purpose: The precise determination of skin's mechanical properties is still an open question. When performing an in vivo test, the piece of skin tested is not as well defined as it is in materialExpand
