The relationship between skin elasticity and viscoelasticity
Elasticity is the ability of the skin to return to its original shape after deformation. In other words, it is the skin's ability to stretch and then recoil. However, in the realm of physics, skin is not just elastic but also exhibits viscoelastic properties.

GloMeca #5 – Above visco-elasticity, hysteresis
The literature says that hysteresis is "a lagging or retardation of the effect, when the forces acting upon a body are changed, as if from velocity or internal friction". From a mechanical point of view, skin can be compared to a composite material with a very-organized...

Beyond BioMechanics, there is mechanotransduction
All living cells depend on their mechanical surroundings. Their structure and function are directly linked to this mechanical stimulus (shear stress, gravity). Cells sense these physical forces by their integrin-based adhesion (“outside-in” and “inside-out”) and translate...
