Clothes woven with electrically conducting threads are a significant step closer with the creation of super-strong carbon nanotube fibres up to 100 metres long. They are stronger than any natural or synthetic organic fibre known.

Materials made from such strong threads could be used to make bullet-proof vests as light as a T-shirt. And their electrical properties could be harnessed to put microsensors into our clothes, measuring everything from temperature to heart rate.

The nanotube threads, created by Ray Baughman and colleagues at the University of Texas, Dallas, and Trinity College, Dublin, have a breaking strain of 570 Joules per gram. This is more than three times stronger than the toughest natural material, spider silk.
