Bionics (from German "Bionik (http://de.wikipedia.org/bionik)" or technique from nature) is application of biological analogies for the study and design of engineering systems. In a more specific meaning, it is a creativity technique that tries to use biological prototypes to get ideas for engineering solutions. This approach is motivated by the fact that biological organisms and their organs have been well optimized by evolution.
Examples of bionics results in engineering include hulls of boats imitating the skin membrane of dolphins, sonar, radar and medical ultrasound imaging imitating echolocation of bats, non_stick coating imitating lotus effect.
Often bionics approach emphasizes imitation of a biological structure rather than a mere implementation of the same function. For example, in computer science, cybernetics tries to model actual organic structures that make us intelligent, while artificial intelligence tries to model the intelligent function regardless of the particular way it can be achieved.
A less common and maybe more recent meaning of the term "bionics" refers to merging organism and machine. This approach results in a hybrid systems combining biological and engineering parts, which can also be referred as cybernetic organism (cyborg). See also implant, prosthesis, and bionics (medical).

The biomedical engineer must be well grounded in biology and physiology and have engineering knowledge that is broad, drawing upon some aspects of electrical and mechanical engineering, in addition to the core areas of chemical engineering.
The chemical engineers used polymer synthesis techniques to design a new material for the storage bag that was capable of "breathing", that is, of allowing carbon dioxide to diffuse out and oxygen to diffuse in, preventing the increase in acidity.
Prior to the involvement of chemical engineers in kidney studies, it was thought that protein leakage was prevented because the holes in the glomerular membrane were smaller than the major protein molecules, so that the capillary wall acted as a sieve.
