DESIGN AND ENGINEERING The devices, or '' Motes ,'' are intended to be the size of a grain of Sand , or even a Dust particle. Each device would contain sensors, computing circuits, bidirectional wireless communications technology and a power supply. Motes would gather data, run computations and communicate using two-way-band radio with other motes at distances approaching 1,000 feet (300 metres). When clustered together, they would automatically create highly flexible, low-power networks with applications ranging from climate control systems to entertainment devices that interact with Information Appliances . The smartdust concept was introduced by Kristofer Pister ( University Of California ) in 2001 , though similar ideas existed in science fiction before then. A recent review discusses various techniques to take smartdust in Sensor Network s beyond millimeter dimensions to the Micrometre level. APPLICATIONS A typical application scenario is scattering a hundred of these sensors around a building or around a hospital to monitor temperature or humidity, track patient movements, or inform of disasters, such as earthquakes. In the military, they can perform as a remote sensor chip to track enemy movements, detect poisonous gas or radioactivity. The ease and low cost of such applications have raised Privacy concerns, primarily in Science Fiction stories. Beyond such demonstrations lies an emerging world of very large networks that combine motes and portable gear with larger technologies to improve the depth, duration and range of monitoring.
