A smart race

Nanorobot swarms are the stuff of sci-fi films, but smart dust is being developed now.

Johan Oomen.
An assembly of microelectromechanical systems or “MEMS”, smart dusts consist of a party of tiny robots that detect light, temperature, vibration, magnetism, or chemicals. They talk to each other via wireless network and employ radio-frequency sensors. Smart dust particles are just a few millimetres across – much like intelligent grains of rice. A dependent species, they have to operate together, like bees, ants, or other colony creatures. And they have their weaknesses too: smart dusts are vulnerable to microwaves, which could electromagnetically disable them.
