Smart dust" devices are tiny wireless microelectromechanical sensors (MEMS) that can detect everything from light to vibrations. Thanks to recent breakthroughs in silicon and fabrication techniques, these "motes" could eventually be the size of a grain of sand, though each would contain sensors, computing circuits, bidirectional wireless communications technology and a power supply. Motes would gather scads of data, run computations and communicate that information using two-way band radio between motes at distances approaching 1,000 feet.

"Last month, Google discovered that it had been the subject of a sophisticated attack on its computer systems, carried out by hackers in search of private data from more than 30 internet companies. Among the targets were the accounts of Chinese human rights activists; experts claimed the hack could be traced to the Chinese government or its proxies. In response, Google announced on Tuesday that it would stop censoring results on Google.cn - the Chinese version of its search engine - or, should Beijing oppose the move, cease operating in China altogether.

The goal for researchers is to get these chips down to 1mm on a side. Current motes are about 5mm, says Kristofer Pister, professor of electrical engineering at UC Berkeley, who's been working with smart dust since 1997.
-
The cost of motes has been dropping steadily. Prices range from $50 to $100 each today, and Pister anticipates that they will fall to $1 within five years.
