In-vivo measurement of mechanical properties of biological materials
Čermáková, Viola ; Kuchařová, Monika (advisor) ; Klemera, Petr (referee)
Measurement of mechanical properties of many biological materials in vivo is based on the assumption that they can be considered as a visco-elastic body. This means that their mechanical properties under dynamic loading response partly to viscous and partly to elastic character. The visco-elastic biological materials include skin, blood walls, vessels, bones, tendons etc. Mechanical properties of biological materials depend on the structure of the material from the molecular to the macroscopic level. They also depend on age and health status of the organism. Obtaining of the standard values of mechanical parameters would be potentially useful as an indicators of functional age of organism also to study the influence of external factors (cosmetics, UV radiation) to changing the properties of biological materials and as well in terms of compatibility with artificial materials. To understand the ongoing processes in the skin, which was chosen as a biological material for measurement of mechanical properties in this thesis, the anatomical and physiological characteristic, including biochemical processes taking place in the synthesis of the main building components of the skin are needed to know. Aging of the skin is a complex biological phenomen consisting of two main parts of the so-called intrinsic...
