“What can smart dust do?
Outfitted with miniature sensors, MEMS can detect everything from light to vibrations to temperature. With an incredible amount of power packed into its small size, MEMS combine sensing, an autonomous power supply, computing and wireless communication in a space that is typically only a few millimeters in volume. With such a small size, these devices can stay suspended in an environment just like a particle of dust.…”
Wireless devices that can monitor just about any environment, as well as store and transmit data are now the size of a grain of salt. These devices have plenty of real-world applications. However, there are some challenging issues to resolve before you see smart dust floating in your neighborhood.
