Biological tissues

They are constituted by different components (i.e. collagen).
Biological soft tissues show a complex 3D-structure (one cell layer cover other cell layers or layers are twisted into one another).
The complex mechanical behaviour in biological soft tissues is characterised by:

Mechanical properties (i.e. elasticity, viscosity, deformability) are depending on the sex, age, health conditions and how long it is in post mortem state. Also the orientation during measurement is important. These mechanical properties are of high interest for constructing PADeMIS.
Most of the characteristic mechanical values available in publications are determined in vitro, but for the movement of the device the local conditions in vivo are important. Therefore, in vivo measurements must be performed.
