Biomimetic
Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. The terms "biomimetics" and "biomimicry" are derived from (''bios''), life, and μίμησις ('' mīmēsis''), imitation, from μιμεῖσθαι (''mīmeisthai''), to imitate, from μῖμος (''mimos''), actor. A closely related field is bionics. Nature has gone through evolution over the 3.8 billion years since life is estimated to have appeared on the Earth. It has evolved species with high performance using commonly found materials. Surfaces of solids interact with other surfaces and the environment and derive the properties of materials. Biological materials are highly organized from the molecular to the nano-, micro-, and macroscales, often in a hierarchical manner with intricate nanoarchitecture that ultimately makes up a myriad of different functional elements. Properties of materials and surfaces result from a complex interpla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bionics
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. The word ''bionic'', coined by Jack E. Steele in August 1958, is a portmanteau from biology and electronics which was popularized by the 1970s U.S. television series ''The Six Million Dollar Man'' and ''The Bionic Woman'', both based on the novel ''Cyborg (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 technology transfer, 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) was inspired by the hydrophobic properties of the Nelumbo, lotus flower plant (the lotus e ...

Janine Benyus
Janine M. Benyus (born 1958) is an American natural sciences writer, innovation consultant, and author. After writing books on wildlife and animal behavior, she coined the term Biomimicry to describe intentional problem-solving design inspired by nature. Her book ''Biomimicry'' (1997) attracted widespread attention from businesspeople in design, architecture, and engineering as well as from scientists. Benyus argues that by following biomimetic approaches, designers can develop products that will perform better, be less expansive, use less energy, and leave companies less open to legal risk. Life Born in New Jersey, Benyus graduated summa cum laude from Rutgers University with degrees in natural resource management and English literature/writing. Benyus has taught interpretive writing and lectured at the University of Montana, and worked towards restoring and protecting wild lands. She serves on a number of land use committees in her rural county, and is president of Living Ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murray's Law
In Biophysics, biophysical fluid dynamics, Murray's law is a potential relationship between Radius, radii at Junction (traffic), junctions in a network of fluid-carrying Cylinder, tubular Pipeline transport, pipes. Its simplest version proposes that whenever a branch of radius r splits into two branches of radii r_1 and r_2, then the three radii should obey the equation r^3 = r_1^3 + r_2^3\textIf network flow is Laminar flow, smooth and leak-free, then systems that obey Murray's law minimize the resistance to flow through the network. For Turbulence, turbulent networks, the law takes the same form but with a different Scaling law, characteristic exponent . Murray's law is observed in the Blood vessel, vascular and respiratory systems of animals, xylem in plants, and the respiratory system of insects. In principle, Murray's law also applies to biomimetics, biomimetic engineering, but human designs rarely exploit the law. Murray's law is named after Cecil D. Murray, a physiologist ...

Hydrophobicity
In chemistry, hydrophobicity is the chemical property of a molecule (called a hydrophobe) that is seemingly intermolecular force, repelled from a mass of water. In contrast, hydrophiles are attracted to water. Hydrophobic molecules tend to be chemical polarity#Nonpolar molecules, nonpolar and, thus, prefer other neutral molecules and nonpolar solvents. Because water molecules are polar, hydrophobes do not dissolution (chemistry), dissolve well among them. Hydrophobic molecules in water often cluster together, forming micelles. Water on hydrophobic surfaces will exhibit a high contact angle. Examples of hydrophobic molecules include the alkanes, oils, fats, and greasy substances in general. Hydrophobic materials are used for oil removal from water, the management of oil spills, and chemical separation processes to remove non-polar substances from polar compounds. The term ''hydrophobic''—which comes from the Ancient Greek (), "having a fear of water", constructed Liddell, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Schmitt
Otto Herbert Schmitt (April 6, 1913 – January 6, 1998) was an American inventor, engineer, and biophysicist known for his scientific contributions to biophysics and for establishing the field of biomedical engineering. Schmitt also coined the term biomimetics and invented or co-invented the Schmitt trigger, the differential amplifier, and the chopper-stabilized amplifier. He was elected in 1953 a Fellow of the American Physical Society. (search on year=1953 and institution=University of Minnesota) He was awarded the John Price Wetherill Medal in 1972.

Velcro
Velcro IP Holdings LLC, trading as Velcro Companies and commonly referred to as Velcro (pronounced ), is a British privately held company, founded by Swiss electrical engineer George de Mestral in the 1950s. It is the original manufacturer of hook-and-loop fasteners, which de Mestral invented. History Swiss electrical engineer George de Mestral who studied at EPFL invented his first touch fastener when, in 1941, he went for a walk in the Jura Mountains, Jura mountains, and wondered why burdock seeds clung to his woolen socks and coat, and also his dog Milka. He discovered it could be turned into something useful. He patented it in 1955, and subsequently refined and developed its practical manufacture until its commercial introduction in the late 1950s. The fastener consisted of two components: a lineal fabric strip with tiny hooks that could 'mate' with another fabric strip with smaller loops, attaching temporarily, until pulled apart. Initially made of cotton, which proved imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nerve Impulse
An action potential (also known as a nerve impulse or "spike" when in a neuron) is a series of quick changes in voltage across a cell membrane. An action potential occurs when the membrane potential of a specific Cell (biology), cell rapidly rises and falls. This depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in several types of Membrane potential#Cell excitability, excitable cells, which include animal cells like neurons and myocyte, muscle cells, as well as some plant cells. Certain endocrine cells such as pancreatic beta cells, and certain cells of the anterior pituitary gland are also excitable cells. In neurons, action potentials play a central role in cell–cell interaction, cell–cell communication by providing for—or with regard to saltatory conduction, assisting—the propagation of signals along the neuron's axon toward axon terminal, synaptic boutons situated at the ends of an axon; these signals can then connect wit ...

The Six Million Dollar Man
''The Six Million Dollar Man'' is an American science fiction and action television series, running from 1973 to 1978, about a former astronaut, USAF Colonel Steve Austin, portrayed by Lee Majors. After being seriously injured in a NASA test flight crash, Austin is rebuilt (at considerable expense, hence the title of the series) with bionic implants that give him superhuman strength, speed and vision. Austin is then employed as a secret agent by a fictional U.S. government office titled OSI. The series was based on Martin Caidin's 1972 novel ''Cyborg'', which was the working title of the series during pre-production. Following three television films intended as pilots, which all aired in 1973, ''The Six Million Dollar Man'' television series aired on the ABC network as a regular episodic series for five seasons from 1974 to 1978. Steve Austin became a pop culture icon of the 1970s. A spin-off television series, ''The Bionic Woman'', featuring the lead female character Jaim ...

Webster's Dictionary
''Webster's Dictionary'' is any of the US English language dictionaries edited in the early 19th century by Noah Webster (1758–1843), a US lexicographer, as well as numerous related or unrelated dictionaries that have adopted the Webster's name in his honor. "''Webster's''" has since become a genericized trademark in the United States for US English dictionaries, and is widely used in dictionary titles. Merriam-Webster is the corporate heir to Noah Webster's original works, which are in the public domain. Noah Webster's ''American Dictionary of the English Language'' Noah Webster (1758–1843), the author of the readers and spelling books which dominated the American market at the time, spent decades of research in compiling his dictionaries. His first dictionary, ''A Compendious Dictionary of the English Language'', appeared in 1806. In it, he popularized features which would become a hallmark of American English spelling (''center'' rather than ''centre'', ''honor'' rat ...
