Bionic arm

Bionics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology.

The word bionic was coined by Jack E. Steele in 1958, possibly originating from the technical term bion (pronounced BEE-on; from Ancient Greek: βίος), meaning 'unit of life' and the suffix -ic, meaning 'like' or 'in the manner of', hence 'like life'. Some dictionaries, however, explain the word as being formed as a portmanteau from biology and electronics. It was popularized by the 1970s U.S. television series The Six Million Dollar Man and The Bionic Woman, both based upon the novel Cyborg by Martin Caidin, which was itself influenced by Steele's work. All feature humans given superhuman powers by electromechanical implants.

The transfer of technology between lifeforms and manufactures 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 the surface of the lotus flower plant is practically unsticky for anything (the lotus effect)..

The term "biomimetic" is preferred when reference is made to chemical reactions. In that domain, biomimetic chemistry refers to reactions that, in nature, involve biological macromolecules (e.g. enzymes or nucleic acids) whose chemistry can be replicated in vitro using much smaller molecules.
