Walking wounded

Military uniforms are getting smarter. Researchers at the Naval Command,
Control and Ocean Surveillance Center in San Diego, California, are developing
polyester trousers for marines that have fibre-optic wires running through them.
If a soldier is shot, a chip connected to the fibres will locate the wound by
sensing which fibres no longer respond. Information will be relayed back to a
command post by a tiny transmitter.
