We all have had our favorite pair of headphones rendered useless by the cable stretching or getting pinched, researchers at North Carolina University have solved those issues for ever.



The team at UNC have developed a conductive wire that can be stretched up to eight times it's original length with out impeding functionality. The stretch-ability was achieved by filling the hollow elastic core of the wire with a liquid metal consisting of gallium and indium.


Keeping the metal materials separate is key to making a much more stretchable wire while keeping electrical conductivity high.The new type of wire is perfect for high stress environment cables such as those used on headphones, cell phone chargers, and USB cables.




At the moment, there is one draw back to the cables as they will leak the liquid metal if the elastic jacket gets punctured.
