...Richard L. Davis was busy trying to devise improvements. One day he let his mind wander and remembered an old mathematical parlor trick, the Möbius loop. * Math suddenly merged with electronics, and Davis had what he was searching for: the design of a noninductive Möbius resistor...
...chew, drink or swallow, Dr. Samuel Adams II, 28, and his associates at Rochester, N.Y.'s Eastman Dental Dispensary, have been bugging the bridgework of volunteers with tiny radio transmitters fitted into dummy teeth. Crammed inside each electronic tooth are a transistor, an induction coil, two capacitors, a resistor and a hearing-aid battery- all miniaturized items developed by the Air Force. Once the radio denture is in place, the subject enters a Faraday cage, a metal-mesh enclosure that blocks out most outside electrical disturbances. As the subject chews and drinks in his static-free environment, his tooth...
Where all the films are removed, the remaining glass is a nonconductor. When a section of tantalum remains, it acts as a resistor. A strip of gold and chromium is a good conductor, and serves as a thin wire. Capacitors can be made by covering tantalum with an oxide that acts as an insulator and then laying on a fresh film of gold. To make a complete circuit, tiny silicon transistors are electrically bonded to the proper sites. Complicated as it is, the process is wholly automatic, and up to one hundred microcircuits can be manufactured on a piece...
