Researchers create headphone cables with a liquid metal

Researchers at North Carolina University have developed a new type of conductive wire that can be stretched up to eight times its original length without impeding functionality! The cable's extreme flexing capability was achieved by putting a liquid metal alloy consisting of gallium and indium into a hollow elastic polymer tube.

This type of stretchable cables may prove to be a real blessing for frequently used devices like headphones as well as phone chargers. The researchers say the cable can be mass-produced using currently available manufacturing methods, but there's still one issue that has to be worked out: when the plastic is split open or cut the metal can leak out.
