Scientists have created wireless bug-shaped microrobots using nanofabrication techniques that turns a 4-inch specialized silicon wafer into a million microscopic robots in just weeks. The microbots, developed by University of Pennsylvania researchers, can walk, survive in harsh environments, and are tiny enough to be injected through an ordinary hypodermic needle, that they may have potential […]
