Smart Dust is a system of tiny microelectromechanical systems (MEMS) which include sensors or robots that are able to detect light, temperature, vibration, magnetism, or chemicals. They are usually operated on a computer network wirelessly and are distributed over an area to perform tasks by sensing through radio-frequency identification.
The concept for this technology came from the Research and Development Corporation (RAND) and a series of governmental studies for potential military applications. This technological advancement was influenced by science fiction authors who mentioned microrobots, artificial swarm intelligence, or necroevolution. Now, this new technology is capable of collecting and transmitting data to and from specific locations. These tiny electronic devices, which are also known as motes, can detect light, vibration, and temperature. Also, the data that is collected by these devices can be uploaded to the Cloud or other remote location for processing.
