Researchers develop self-healing electronics, adamantium sadly not included
In today's feature-laden electronics devices, the failure of one little electronic component can scuttle the entire package. To make matters worse, if the damage happens to strike something like a multilayer integrated circuit, then you pretty much need to replace the whole computer chip. But what if the chip could repair itself like a certain vertically challenged Canadian mutant? That's exactly what researchers at the University of Illinois at Urbana-Champaign managed to do after placing self-healing polymers on top of a gold circuit. Once a break occurred, microcapsules with liquid metal filled the crack and restored 99 percent of conductivity in mere microseconds. Self-healing electronics would especially be helpful on things like aircraft, where miles of conductive wires can make finding a break difficult, researchers said. The research is just the latest in a field that also has seen self-healing sensors and shape-memory polymers, but sadly, there's still no word on using this stuff to self-heal a broken heart....
Self-healing polymer serves up quick fixes under UV rays (video)
As many self-healing polymers as we've seen roll across our screens, we never really tire of them -- chalk it up to our unending quest for perfection, but we like our gadgets devoid of nicks and scratches. Lucky for us, a team of scientists that shares our need for clean has produced a material that fixes its imperfections in a mere 60 seconds when exposed to UV light. The typically rigid material basically melts down when exposed to rays of a specific wavelength, allowing it to fill in any nicks or dings. When the light is lifted, the polymer goes back to its original form, and voila -- the surface is like new. Its creators say the material could be used on everything from cars to dining room tables, but we've already come up with laundry list of devices that could do with a truly scratch resistant surface. Video of the stuff in action after the break.
