cutaneous anisotropy

Glomeca #7 – Cutaneous anisotropy

Here we will talk about a term which needs to be elucidated : anisotropy. Skin is described as an anisotropic soft material but it is essential to explain further to well understand how to use this term..

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...

How’s AFM a fantastic tool in cancer research?

Atomic Force Microscopy (AFM) allows studies of biological samples and molecules with atomic resolution under near-physiological condition. Cells, under external stimuli or any physiological modifications, bear physicochemical properties changes that directly affect...

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...

Biomechanics and Mechanobiology

Biomechanics uses mechanical and physics principles to understand biological systems as structure of human cells, tissues or organs. Mechanobiology studies the way how physical forces in cell or tissue can contribute to develop changes or even diseases...

Stress and strain

Our body, our organs, ours cells are submitted to mechanical stress. The influence of mechanical stress of living organisms is omnipresent. It depends not only on environmental and endogenous loads (pressure exerted by cavities and blood) but also on intrinsic mechanical...

A brief manual of biomechanics

Stress, strain, relaxation, elastic modulus, viscoelasticity, dissipation…The feeling of hearing “blah blah blah” when you hear about biomechanics? No stress! We are decoding for you the physics terms important to the understanding of the properties of biological...
