In the classic sci-fi film "2001: A Space Odyssey," the evil computer Hal 9000 is finally defeated when a courageous scientist disconnects Hal's internal processing units. But if researchers from North Carolina State University in Raleigh succeed in bringing their self-healing wire to market, Hal could live again.
Their electricity-conducting live wire contains a core of liquid metal — a fluid alloy of gallium and indium — according to Gizmag.com. The liquid is housed within a polymer sheath that's also stretchable, giving the wire some additional functionality.
If the wire is cut, the liquid alloy oxidizes, forming a hard crust. "Think of it in the same way the blood clots to create a scab so we don't bleed to death when we're cut," Treehugger.com reports.
