[Gizmag] Stretchable electrical wires heal back together after being severed

post #1 of 15

Quote:
Last month, we heard about how a team led by North Carolina State University’s Dr. Michael Dickey had created an electrical wire that could be stretched up to eight times its regular length ... and still carry a current. This was possible thanks to a conductive liquid metal alloy of gallium and indium, contained inside the wire’s elastic polymer outer housing. Now, Dickey's team has developed a new wire that not only can be stretched, but that will heal itself when severed.

Finally... soldering I can't screw up biggrin.gif

I sure hope they don't use these in any prototype Terminator-like machines for war rolleyes.gif

On a more serious note, that's really neat. The things they keep coming up with these days blow me away every time biggrin.gif

It seems the idea here is that the polymer that surrounds the metal is self-healing. I don't see this being easily applicable in your typical wires

That actually makes me wonder about if this material would sound good in audio use. We know how copper sounds, but how would a liquid metal alloy sound? My guess would be that there will be inherent distortions in the audio from the fluidity of the conductor material.
