Scientists Develop 'Smart Dust' for Room Surveillance
Scientists are developing 'smart dust,' tiny sensors inspired by science fiction, capable of drifting through the air to collect data for various applications, including military and environmental uses. These micro-sensors have advanced significantly over decades, becoming nearly invisible and capable of detecting a wide range of variables, with industry growth expected to reach nearly $400 million by 2032. While promising, the technology raises concerns about privacy, geoengineering, and ethical implications.
