Rubber wires can stretch up to 8 times

Researchers at the University of North Carolina (USA) have successfully studied a type of electrical wire that can stretch up to 8 times like any elastic cord. After so many stretches, the 'rubber wire' still retains its technical features.

New type of wire can be elastic like rubber.

This invention opens a broad perspective for the electronics industry in many applications, from headphones to tailor-made "smart" clothes to electronic circuits.

To produce these wires, the use of elastic polymer micro-tubes, which contain liquid alloys of two metals, gallium and inium liquid, are excellent conductors of electricity.

Previously, scientists had intended to create elastic conductors by 'weaving' metal wires into elastic polymers but not achieving the desired results. The resulting product cannot combine durability and elasticity.

The new conductor retains the properties of the original materials, both high strength and good elasticity with superior electrical conductivity.

The production of these new wires does not require complicated technological processes and the price is not too high. But there is also a problem that inventors need to overcome, which is to prevent metal leakage to a minimum whenever the wire is broken.
