High-Resolution Elastography for Thin-Layer Mechanical Characterization: Toward Skin Investigation.
Preliminary in vivo experiments conducted on forearm and cheek skin revealed the promising performance of HF-TE in measuring elasticity in the dermis and hypodermis, which are the two human skin layers of interest in this study. Expand

An innovative approach based on a rotary tribometer coupled with laser velocimetry for measuring the elastic wave propagation on the skin is proposed. Expand
Assessment of Mechanical Properties of Skin by Shearwave Propagation and Acoustic Dispersion
In this chapter, we present a methodology of documenting the angular anisotropy of skin elasticity with high sensitivity and dynamic range using the Reviscometer® RVM 600 and its use to documentExpand
Assessment of elastic parameters of human skin using dynamic elastography
A new high-resolution device capable of measuring local Young's modulus in very thin layers (1-5 mm) and devoted to the in vivo evaluation of the elastic properties of human skin is described and found to be higher in the dermis than in the hypodermis and other soft tissues. Expand
Le palpeur acoustique : un nouvel outils d'investigation des tissus biologiques
L'objectif de ce travail est de developper les applications du palpeur acoustique, dedie a la mesure d'elasticite des tissus biologiques. La validation de cet outil dans des materiaux d'etudes etantExpand
Age- and body mass index-related changes in cutaneous shear wave velocity
The intrinsic skin tension lines identified by the minimum RRTM are not significantly altered with age and BMI variations, but skin laxity identified by larger maximum and mean multidirectional R RTM may increase after 60 years of age in subjects with a normal BMI. Expand
Influence of Body Posture and Gravitational Forces on Shear Wave Propagation in the Skin
Shear wave propagation may be a convenient non-invasive tool to better identify the natural skin tension lines in the skin, thus refining the orientation of incision during cutaneous surgery. Expand
Evaluation of skin viscoelasticity and anisotropy by measurement of speed of shear wave propagation with viscoelasticity skin analyzer.
In healthy human subjects of both sexes significant variations in skin stiffness and anisotropy were observed in three different skin areas along the forearms, but the speed of elastic shear wave propagation was similar in the symmetric contralateral areas. Expand
