Chinese scientists have developed a kind of cable using nanometer technology that is as thin as four thousandths of a single hair.

Experts say the new cable would have to be magnified over ten thousand times to be as thick as ordinary cable and it's much cheaper and easier to produce.

The new cable can be applied to a wider range of uses than thick cable, especially in computers and other high-tech products.
