Smart Dust
The applications of Round 1 turned in and my little project simmering down, I took the day today to browse the web to look at the some of the innovations being spawned in the labs around the world. The next phase of innovation will be driven by the ubiquitous nature and integration of sensors networks and our ability to discern useful information from the data. One such concept is the "smart dust" concept - a distributed sensor network that can sense and trasmit data.. More information can be found here.
Picture being able to scatter hundreds of tiny sensors around a building to monitor temperature or humidity. Or deploying, like pixie dust, a network of minuscule, remote sensor chips to track enemy movements in a military operation. "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. Potential commercial applications are varied, ranging from catching manufacturing defects by sensing out-of-range vibrations in industrial equipment to tracking patient movements in a hospital room.
