Coronavirus: how this virus can affect our largest organ, the skin?
There's no need here to list the usual clinical manifestations of COVID-19 infection. They are many and sadly may lead to acute respiratory distress syndrome and death. Let's focus on a special topic : our skin. The skin symptoms have been poorly described...

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...

GloMeca #4 – Skin mechanical behaviour through lifespan
From a biomechanical point of view, ageing is a very complex process that seriously affects the functions of all organs and tissues of the body, and most often has irreversible effects on their mechanical behaviour. The most visible effects of ageing can be observed in...

GloMeca #3 – Skin elasticity: From Hooke’s law to Young’s modulus
Skin is made up of different layers (epidermis, dermis, hypodermis) and is regularly exposed to all kind of stress. As those layers have different composition and thickness, each of them has a specific mechanical role...

GloMeca #1 – Visco-elasticity
According a physicist, skin is considered as a multi-layer material composed by dermis, epidermis and hypodermis. Skin mechanical properties are mainly linked to the dermis which is composed by collagen fibers networks and elastics fibers. During aging, these fibers tend...
