When we hear the word “dust”, the first thing that comes to our mind is a powdery substance with zero value. Smart dust is a tiny device with extensive applications in science and technology. Designing a product of tiny or compact size with various intrinsic applications is a recent trend in technology, especially in electronics. This article discusses the technological advancements and applications of smart dust.
Smart dust is a few millimeter-sized device that can operate as an individual component using a very small power supply. It consists of multiple small wireless microelectromechanical systems (MEMS) of 20 micrometers-1 millimeters in size. MEMS are also known as motes which are equipped with sensors, cameras, and other communication mechanisms. These are ultimately connected to a computer network wirelessly to process the data procured through RFID (radio-frequency identification) technology. These minuscule devices are constructed using conventional silicon microfabrication techniques and can remain suspended in an environment similar to dust.
