Smart dust definition
Smart dust consists of tiny microelectromechanical systems (MEMS) like sensors and robots that can detect environmental factors such as light, temperature, and chemicals. Equipped with wireless communication, these miniature devices can network and transmit data to a central point.

History of smart dust
The concept of smart dust emerged in the early 1990s, initially conceptualized at a RAND workshop. Officially coined at the University of California, Berkeley, in the late 1990s by Kris Pister and his team, the term referred to microscopic sensors capable of detecting environmental factors.
DARPA funded these researchers to create tiny, wireless sensor networks for uses like battlefield surveillance. With technological advances in microfabrication and wireless communication, the applications of smart dust have expanded beyond the military to environmental monitoring, healthcare, and industry.
Use cases of smart dust
- Environmental monitoring. Smart dust can be deployed in various ecosystems to monitor environmental conditions like temperature, humidity, and pollutant levels.
- Agricultural optimization. In agriculture, smart dust sensors can monitor soil conditions, crop health, and microclimates, providing precise data for optimized irrigation, fertilization, and pest control.
- Healthcare applications. In the healthcare sector, smart dust offers the potential for non-invasive monitoring of bodily functions and targeted drug delivery. Tiny sensors could track internal body conditions or release medication at targeted sites.
