The new science of claytronics, which will use nanotechnology to create tiny robots called catoms, should enable three-dimensional copies of people to be "faxed" around the world for virtual meetings.

A doctor could also consult with a patient over the phone, even taking their pulse by holding the wrist of the claytronic replica, reports New Scientist.

And the nano "clay" could be carried around, shape-shifting into virtually anything when required. Your claytronic mobile phone could turn into a hammer for a spot of DIY and then a pair of shoes to go jogging. The creator, Dr Todd Mowry, director of Intel's research labs in Pittsburgh, Pennsylvania, said: "You could have a little lump of this stuff you carry around and it could be a million different things. It's like the world's ultimate Swiss army knife." His partner, Dr Seth Goldstein, of Carnegie Mellon University in Pittsburgh, said: "It's absolutely going to work."

Intel's robotics expert, Jason Campbell, added: "The more you look at it, the more likely it seems we will be able to manufacture these things.
