Yep, that’s what researchers over at North Carolina State University say they have come up with. They said, “The researchers first created tiny tunnels, called microfluidic channels, in a commercially available self-healing polymer using solid wire. By filling those channels with a liquid-metal alloy of indium and gallium, they were able to create a liquid-metal wire in an elastic sheath. Because the wire is liquid, it can be stretched along with the polymer sheath.” These liquids create a barrier, much like blood does when it clots, to keep from leaking out when severed, and once placed back together they reconnect.
Stretchable and self healing wiring?
