Broken wires are about to be a thing of the past.
Researchers at North Carolina State University have developed elastic, self-healing wires that could be used in technologies that are exposed to high-stress environments.
They made these wires by first creating tiny tunnels in a self-healing polymer sheath. They then filled the tunnels with a liquid metal alloy made of indium and gallium, which they used to make a liquid metal wire in an elastic sheath.
