{{Short description|System of microelectromechanical devices}}
'''Smartdust'''<ref>''More than Meets the eye''. PC Mag. Mar 12, 2002. Page 30.</ref> 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 [[chemical]]s. They are usually operated on a [[computer network]] [[wireless]]ly and are distributed over some area to perform tasks, usually sensing through [[radio-frequency identification]]. Without an antenna of much greater size the range of tiny smart dust communication devices is measured in a few [[millimeter]]s and they may be vulnerable to electromagnetic disablement and destruction by microwave exposure.
