Introduction:
A cyborg (short for "cybernetic organism") is a being with both organic and biomechatronic body parts. The term was coined in 1960 by Manfred Clynes and Nathan S. Kline.
The term cyborg is not the same thing as bionic, biorobot or android; it applies to an organism that has restored function or enhanced abilities due to the integration of some artificial component or technology that relies on some sort offeedback. While cyborgs are commonly thought of as mammals, including humans, they might also conceivably be any kind of organism. It is hypothesized that cyborg technology will form a part of postbiological evolution, in the form oftranshumanism - where people are artificially enhanced beyond their original biological characteristics.
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." In popular culture, 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); as almost indistinguishable from humans (e.g., the "Human" Cylons from the re-imagining of BattlestarGalactica 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).
Overview:
According to some definitions of the term, the physical attachments humanity has with even the most basic technologies have already made them cyborgs. In a typical example, a human with an artificial cardiac pacemaker or implantable cardioverter-defibrillator would be considered a cyborg, since these devices measure voltage potentials in the body, perform signal processing, and can deliver electrical stimuli, using this synthetic feedback mechanism to keep that person alive. Implants, especially cochlear implants, that combine mechanical modification with any kind of feedback response are also cyborg enhancements. Some theoristscite such modifications as contact lenses, hearing aids, or intraocular lenses as examples of fitting humans with technology to enhance their biological capabilities. As cyborgs currently are on the rise some theorists argue there is a need to develop new definitions of aging and for instance a bio-techno-social definition of aging has been suggested.
Origins:
The concept of a man-machine mixture was widespread in science fiction before World War II. As early as 1843, Edgar Allan Poe described a man with extensive prostheses in the short story "The Man That Was Used Up". In 1908, Jean de la Hire introduced Nyctalope (perhaps the first true superhero was also the first literary cyborg) in the novel L'Homme Qui Peut Vivre DansL'eau (The Man Who Can Live in the Water). Edmond Hamilton presented space explorers with a mixture of organic and machine parts in his novel The Comet Doom in 1928. He later featured the talking, living brain of an old scientist, Simon Wright, floating around in a transparent case, in all the adventures of his famous hero, Captain Future. He uses the term explicitly in the 1962 short story, "After a Judgment Day," to describe the "mechanical analogs" called "Charlies," explaining that "[c]yborgs, they had been called from the first one in the 1960s...cybernetic organisms." In the short story "No Woman Born" in 1944, C. L. Moore wrote of Deirdre, a dancer, whose body was burned completely and whose brain was placed in a faceless but beautiful and supple mechanical body.
The term was coined by Manfred E. Clynes and Nathan S. Kline in 1960 to refer to their conception of an enhanced human being who could survive in extraterrestrialenvironments:
“For the exogenously extended organizational complex functioning as an integrated homeostatic system unconsciously, we propose the term 'Cyborg'. - Manfred E. Clynes and Nathan S. Kline”
Cyborgs tissues in engineering:
Cyborgs tissues structured with carbon nanotubes and plant or fungal cells have been used in artificial tissue engineering to produce new materials for mechanical and electrical uses. The work was presented by Di Giacomo and Maresca at MRS 2013 Spring conference on Apr, 3rd, talk number SS4.04. The cyborg obtained is inexpensive, light and has unique mechanical properties. It can also be shaped in desired forms. Cells combined with MWCNTs co-precipitated as a specific aggregate of cells and nanotubes that formed a viscous material. Likewise, dried cells still acted as a stable matrix for the MWCNT network. When observed by optical microscopy the material resembled an artificial “tissue” composed of highly packed cells. The effect of cell drying is manifested by their “ghost cell” appearance. A rather specific physical interaction between MWCNTs and cells was observed by electron microscopy suggesting that the cell wall (the most outer part of fungal and plant cells) may play a major active role in establishing a CNTs network and its stabilization. This novel material can be used in a wide range of electronic applications from heating to sensing and has the potential to open important new avenues to be exploited in electromagnetic shielding for radio frequency electronics and aerospace technology. In particular using Candida albicans cells cyborg tissue materials with temperature sensing properties have been reported.
Animal cyborgs:
The US-based company Backyard Brains released what they refer to as "The world's first commercially available cyborg" called the RoboRoach. The project started as a University of Michigan biomedical engineering student senior design project in 2010 and was launched as an available beta product on 25 February 2011.
Social cyborgs:
More broadly, the full term "cybernetic organism" is used to describe larger networks of communication and control. For example, cities, networks of roads, networks of software, corporations, markets, governments, and the collection of these things together. A corporation can be considered as an artificial intelligence that makes use of replaceable human components to function. People at all ranks can be considered replaceable agents of their functionally intelligent government institutions, whether such a view is desirable or not. The example above is reminiscent of the "organic paradigm" popular in the late 19th century due to the era's breakthroughs in understanding of cellular biology.
