Scientists at North Carolina State University have developed a special wire for headphones that can stretch up to eight times its original length while still delivering sound.
The wire has a special liquid metal alloy made from gallium and indium. The only problem: If the wire’s casing breaks, the liquid metal could leak out.
In a research paper, the researchers say the liquid metal wire could also be used for electronic textiles or gadget chargers.
Thanks to Engadget for finding this.
