Bionic is based on the assumption, that nature optimized structures and processes based on evolutionary developments, of which men may learn and start to imitate.
The transfer of technology between lifeforms and manufactured objects is, according to proponents of bionic technology, desirable because evolutionary pressure typically forces living organisms, including fauna and flora, to become highly optimized and efficient. A classical example is the development of dirt- and water-repellent paint (coating) from the observation that practically nothing sticks to the surface of the lotus flower plant (the lotus effect)
As an interdisciplinary field of research, bionics attracts natural scientists, engineers, architects, philosophers and designers. Bionics is concerned with the systematic recognition of solutions in living nature. Its goal is always a technical object or process separate from nature.
