UNDERSKIN - A device for measuring cutaneous tension

This device allows to measure the natural mechanical tension of a cutaneous tissue, on the surface and in depth. This measurement can be carried out in vivo on a healthy or sick individual, and in vitro on tissues obtained from biopsies or made by bio-printing. It is non-invasive, reliable and reproducible. It provides a map of mechanical properties as a function of the depth of the skin. It is in particular possible to visualize in the skin sub-layers, the effect of aging, the effect of a cream or even the state of tension of stretch marks. In addition, this device also makes it possible to ensure the monitoring of a scar, or to help in the diagnosis of pathologies due to a failure of the collagen fibers network (Ehlers-Danlos, Cutis-Laxa , scleroderma, ...)
