10 Groundbreaking Surveillance Systems That Are Revolutionizing Observation

8. Neural Dust Monitoring Networks

Thousands of millimeter-sized devices make up these tiny sensor networks, which may be placed all around for thorough observation. Miniaturised sensors, CPUs, and communication systems run on ambient electromagnetic energy each "neural dust" particle carries.

Among the several factors the network may track are temperature, pressure, chemical composition, and electromagnetic fields. Providing comprehensive data from once unreachable sites, this technique finds uses in structural health monitoring, environmental sensing, and medical diagnostics.
