abstract:Smartdust is a system of many tiny microelectromechanical systems (MEMS) such as sensors, robots, or other devices, that can detect, for example, light, temperature, vibration, magnetism, or chemicals. They are usually operated on a computer network wirelessly and are distributed over some area to perform tasks, usually sensing through radio-frequency identification.
Unlike intelligent tags and the idea of a 'smart dust' -- sensor devices in all objects and appliances that are always 'on' -- the person wearing a sensor-enabled coat would be able to choose with whom or what it interacts with.
