Ultrasonic Techniques Used to Viscoelastic Nonlinearity Characterization of Human Skin Under Loading in-vivo

Popis výsledku v původním jazyce

Human skin tissue represents complicated bio-polymeric material with very complex mechanical behavior, highly dependent on a large number of living and environmental factors. Skin tissue is anisotropic and exhibits highly nonlinear, viscoelastic responsewith memory, hysteresis and hardening/softening effects during the loading. Mechanical behavior of human skin is of great interest in dermatology, plastic surgery and cosmetics. Small changes in the mechanical properties are very sensitively reflectingmany diseases. This contribution deals with noninvasive ultrasonic investigation of nonlinear viscoelastic behavior changes during the tensile in-vivo loading and relaxation of the skin. Viscoelastic properties are evaluated from relaxation curves and characterized with parameters of 5-element rheological model. Linear ultrasonic parameters like velocity and attenuation are evaluated from direct propagating waves. Instantaneous elastic modules are obtained from ultrasonic measurements an
