Bionics or biologically inspired engineering is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology.[1]

The word bionic, coined by Jack E. Steele in August 1958, is a portmanteau from biology and electronics[2] that 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. All three stories feature humans given various superhuman powers by their electromechanical implants.

According to proponents of bionic technology, the transfer of technology between lifeforms and manufactured objects is desirable because evolutionary pressure typically forces living organisms–fauna and flora–to become optimized and efficient. For example, dirt- and water-repellent paint (coating) developed from the observation that practically nothing sticks to the surface of the lotus flower plant (the lotus effect).[3]

The term "biomimetic" is preferred for references to chemical reactions,[citation needed] such as reactions that, in nature, involve biological macromolecules (e.g., enzymes or nucleic acids) whose chemistry can be replicated in vitro using much smaller molecules.

Examples of bionics in engineering include the hulls of boats imitating the thick skin of dolphins; sonar, radar, and medical ultrasound imaging imitating animal echolocation.

In the field of computer science, the study of bionics has produced artificial neurons, artificial neural networks,[4] and swarm intelligence. Bionics also motivated advancement in Evolutionary computation but took the idea further by simulating evolution in silico and producing well-optimized solutions that had never appeared in nature.

A 2006 research article estimated that "at present there is only a 12% overlap between biology and technology in terms of the mechanisms used".[5][clarification needed]


The name "biomimetics" was coined by Otto Schmitt in the 1950s. The term "bionics" was coined by Jack E. Steele in August 1958 while working at the Aeronautics Division House at Wright-Patterson Air Force Base in Dayton, Ohio.[6] However, terms like biomimicry or biomimetics are preferred in order to avoid confusion between the medical term "bionics." Coincidentally, Martin Caidin used the word for his 1972 novel Cyborg, which was adapted into the television film and subsequent series The Six Million Dollar Man. Caidin was a long-time aviation industry writer before turning to fiction full-time.


Velcro was inspired by the tiny hooks found on the surface of burs.

The study of bionics often emphasizes implementing a function found in nature rather than imitating biological structures. For example, in computer science, cybernetics tries to model the feedback and control mechanisms that are inherent in intelligent behavior, while artificial intelligence tries to model the intelligent function regardless of the particular way it can be achieved.

The conscious copying of examples and mechanisms from natural organisms and ecologies is a form of applied case-based reasoning, treating nature itself as a database of solutions that already work. Proponents argue that the selective pressure placed on all natural life forms minimizes and removes failures.

Although almost all engineering could be said to be a form of biomimicry, the modern origins of this field are usually attributed to Buckminster Fuller and its later codification as a house or field of study to Janine Benyus.

There are generally three biological levels in the fauna or flora, after which technology can be modeled:

In medicine

Bionics refers to the flow of concepts from biology to engineering and vice versa. Hence, there are two slightly different points of view regarding the meaning of the word.

In medicine, bionics means the replacement or enhancement of organs or other body parts by mechanical versions. Bionic implants differ from mere prostheses by mimicking the original function very closely, or even surpassing it.

Bionics' German equivalent, Bionik, always adheres to the broader meaning, in that it tries to develop engineering solutions from biological models. This approach is motivated by the fact that biological solutions will usually be optimized by evolutionary forces.

While the technologies that make bionic implants possible are developing gradually, a few successful bionic devices exist, a well known one being the Australian-invented multi-channel cochlear implant (bionic ear), a device for deaf people. Since the bionic ear, many bionic devices have emerged and work is progressing on bionics solutions for other sensory disorders (e.g. vision and balance). Bionic research has recently provided treatments for medical problems such as neurological and psychiatric conditions, for example Parkinson's disease and epilepsy.[19]

In 1997, Colombian researcher Alvaro Rios Poveda developed an upper limb and hand prosthesis with sensory feedback. This technology allows amputee patients to handle prosthetic hand systems in a more natural way.[20]

By 2004 fully functional artificial hearts were developed. Significant progress is expected with the advent of nanotechnology. A well-known example of a proposed nanodevice is a respirocyte, an artificial red cell, designed (though not built yet) by Robert Freitas.

During his eight years in the Department of Bioengineering at the University of Pennsylvania, Kwabena Boahen developed a silicon retina that was able to process images in the same manner as a living retina. He confirmed the results by comparing the electrical signals from his silicon retina to the electrical signals produced by a salamander eye while the two retinas were looking at the same image.

On 21 July 2015, the BBC's medical correspondent Fergus Walsh reported, "Surgeons in Manchester have performed the first bionic eye implant in a patient with the most common cause of sight loss in the developed world. Ray Flynn, 80, has dry age-related macular degeneration which has led to the total loss of his central vision. He is using a retinal implant that converts video images from a miniature video camera worn on his glasses. He can now make out the direction of white lines on a computer screen using the retinal implant." The implant, known as the Argus II and manufactured in the US by the company Second Sight Medical Products, had been used previously in patients who were blind as the result of the rare inherited degenerative eye disease retinitis pigmentosa.[21]

In 2016,Tilly Lockey (born 7 October 2005) was fitted with a pair of bionic "Hero Arms" manufactured by OpenBionics, a UK bionics enterprise. The Hero Arm is a lightweight myoelectric prosthesis for below-elbow amputee adults and children aged eight and above. Tilly Lockey, who at 15 months had both of her arms amputated after being diagnosed with meningococcal sepsis strain B, describes the Hero Arms as “really realistic, to the point where it was quite creepy how realistic they were.” [22]

On 17 February 2020, Darren Fuller, a military veteran became the first person to receive[23] a bionic arm. Fuller lost the lower section of his right arm while serving term in Afghanistan during an incident that involved mortar ammunition in 2008.


A political form of biomimicry is bioregional democracy, wherein political borders conform to natural ecoregions rather than human cultures or the outcomes of prior conflicts.

Critics of these approaches often argue that ecological selection itself is a poor model of minimizing manufacturing complexity or conflict, and that the free market relies on conscious cooperation, agreement, and standards as much as on efficiency – more analogous to sexual selection. Charles Darwin himself contended that both were balanced in natural selection – although his contemporaries often avoided frank talk about sex, or any suggestion that free market success was based on persuasion, not value.

Advocates, especially in the anti-globalization movement, argue that the mating-like processes of standardization, financing and marketing, are already examples of runaway evolution – rendering a system that appeals to the consumer but which is inefficient at use of energy and raw materials. Biomimicry, they argue, is an effective strategy to restore basic efficiency.

Biomimicry is also the second principle of Natural Capitalism.

Other uses

Business biomimetics is the latest development in the application of biomimetics. Specifically it applies principles and practice from biological systems to business strategy, process, organisation design and strategic thinking. It has been successfully used by a range of industries in FMCG, defence, central government, packaging and business services. Based on the work by Phil Richardson at the University of Bath[24] the approach was launched at the House of Lords in May 2009.

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. In chemistry, a biomimetic synthesis is a chemical synthesis inspired by biochemical processes.

Another, more recent meaning of the term bionics refers to merging organism and machine. This approach results in a hybrid system combining biological and engineering parts, which can also be referred as a cybernetic organism (cyborg). Practical realization of this was demonstrated in Kevin Warwick's implant experiments bringing about ultrasound input via his own nervous system.
