A cyborg, short for "cybernetic organism", is a being with both organic and mechanical parts. See for example biomaterials and bioelectronics. The term was coined in 1960 by Manfred Clynes and Nathan S. Kline.[1] D. S. Halacy's Cyborg: Evolution of the Superman in 1965 featured an introduction which spoke of a "new frontier" that was "not merely space, but more profoundly the relationship between 'inner space' to 'outer space' – a bridge...between mind and matter."[2]

The beginning of Cyborg creation began when HCI (human-computer interaction) began. There is a clear distinction between the human and computerized technology in HCI, which differs from cyborgs in that cyborgs act out human functions.

The term cyborg is often applied to an organism that has enhanced abilities due to technology,[3] though this perhaps oversimplifies the necessity of feedback for regulating the subsystem. The more strict definition of Cyborg is almost always considered as increasing or enhancing normal capabilities. While cyborgs are commonly thought of as mammals, they might also conceivably be any kind of organism and the term "Cybernetic organism" has been applied to networks, such as road systems, corporations and governments, which have been classed as such. The term can also apply to micro-organisms which are modified to perform at higher levels than their unmodified counterparts. It is hypothesized that cyborg technology will form a part of the future human evolution.

Some cyborgs are portrayed as a synthesis of organic and synthetic parts, and frequently pose the question of difference between human and machine as one concerned with morality, free will, and empathy. Some cyborgs may be represented as visibly mechanical (e.g. the Cybermen in the Doctor Who franchise or The Borg from Star Trek or Darth Vader from Star Wars); or as almost indistinguishable from humans (e.g. the Terminators from the Terminator films, the "Human" Cylons from the re-imagining of Battlestar Galactica etc.) The 1970s television series The Six Million Dollar Man featured one of the most famous fictional cyborgs, referred to as a bionic man; the series was based upon a novel by Martin Caidin titled Cyborg. Cyborgs in fiction often play up a human contempt for over-dependence on technology, particularly when used for war, and when used in ways that seem to threaten free will. Cyborgs are also often portrayed with physical or mental abilities far exceeding a human counterpart (military forms may have inbuilt weapons, among other things).
