NC State builds stretchable wires from liquid metal, keeps headphones humming (video)
More than a few of us have had that moment of panic when our headphone cords catch on an object and cut the listening short -- sometimes permanently. Researchers at North Carolina State University could help mitigate those minor musical catastrophes with wiring that stretches up to eight times its normal length. The method fills an elastic polymer tube with a liquid gallium and indium alloy that delivers the electricity. By keeping the materials separate, unlike many past attempts, the solution promises the best of both worlds: the conduction we need, and the tolerance for tugs that we want. NC State already has an eye on stretchable headphone cords, as you'll see in the video after the break, but it also sees advantages for electronic textiles that could endure further abuse. As long as the team can eventually solve a problem with leakage when there's a complete break, we'll be glad enough to leave one of our common audio mishaps in the past.

NCSU creates stretchable conductors from silver nanowires, lets gadgets go the extra inch
As often as we've seen flexible electronics, there haven't been many examples that could stretch -- a definite problem for wearables as well as any gadget that could afford to take a pull or squeeze. North Carolina State University's Yong Zhu and Feng Xu may have covered this gap through a form of silver nanowire conductor that keeps the energy flowing, even if the wire is stretched as much as 50 percent beyond its original length. By coating the nanowires with a polymer that traps the silver when solid, the researchers create an elastic material that can crumple and let the nanowire take the strain without interruption. Although the stretchy conductor's nature as a research project could put any practical use years into the future, Zhu notes that it can take loads of abuse, making it a perfect fit for rugged mobile devices. It should also allow for robots with a gentler touch and a more natural look... although we'll admit we're skittish about the creepy androids likely to follow.
