Minnesota has long been known to host numerous biomedical companies as is indicated by the University of Minnesota listing of more than 1200 biomedical engineering-related industries in Minnesota. Click here to see their MBBNet Industry database.
Bionics (also known as biomimetics, biognosis, biomimicry, or bionical creativity engineering) is the application of methods and systems found in nature to the study and design of engineering systems and modern technology.Some dictionaries, however, explain the word as being formed from “biology” + “electronics”.
The transfer of technology between lifeforms and synthetic constructs is desirable because evolutionary pressure typically forces natural systems 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). Examples of bionics in engineering include the hulls of boats imitating the thick skin of dolphins; sonar, radar, and medical ultrasound imaging imitating the echolocation of bats.
Electrical biosignals (“bio-electrical” signals) are usually taken to be (changes in) electrical currents produced by the sum of electrical potential differences across a specialized tissue, organ or cell system like the nervous system. Thus, among the best-known bio-electrical signals are :
