Structural bionics involves multi-disciplines, such as botany, plant physiology, soil science, optics, biophysics, biochemistry, physics, electronics, ergonomics, psychology, materials science, mechanics, dynamics, control theory, engineering, economics, color, aesthetics, communication, ethics and social science.
However, the human-made materials were quite different from the materials made by natural organisms.
Polymer materials from biomimetic materials are degradable and environment friendly.
Intelligent materials refer to the “live” materials that have the similar structures and functions with biological materials.

Fatigue strength of a sliding bearing depends on many factors such as mechanical properties of bearing materials, structure of lining and design features of the whole bearing unit.
The bearing machine SMOK meets requirements of ISO 7905-1 standard [3] in relation to fatigue testing of slide journal bearings.
The journal movement is accompanied by lubricant squeeze effect.
This work has been financed from budget sources on science in 2011 year as a research project (grant) No N N504 340136.
