Dear Hagai Eshel,
One source of information about this topic can be obtained from papers
published by A.H. Hoffman and P. Grigg (i.e., do a medline search on their
names). Grigg has published one study [Grigg P (1996) Stretch sensitivity
of mechanoreceptor neurons in rat hairy skin. J Neurophysiol 76(5):2886-95]
in which he reports the 2D stiffness moduli for rat hairy skin. In other
studies co-authored by Grigg and myself, we found that to achieve a
"pseudo-elastic" state, we had to pre-condition rat skin by stretching it
about 10 times at physiological levels of load.
