Scientists Develop “Smart Dust” — Microscopic Sensors That Can Float in Air Researchers have developed a new class of microscopic sensors known as “Smart Dust”, made using advanced MEMS (micro-electromechanical systems) technology. These particles are so small they can be suspended in air or embedded into environments, where they collect data such as temperature, light, vibration, pressure, or chemical traces. Smart dust is designed primarily for scientific, industrial, and environmental monitor

Coming to air near you ✈️💨 Smart dust refers to tiny, wireless microelectromechanical sensors (MEMS) capable of monitoring, recording, and transmitting data about their environment. DARPA (Defense Advanced Research Projects Agency) began developing smart dust in the early 1990s to enhance military surveillance. Initially designed for battlefield intelligence, these minuscule devices can now be used for tracking human movements discreetly. Smart dust particles are small enough to evade detection
