Rutgers University-New Brunswick researchers found common Wi-Fi technology can easily identify weapons, bombs, and explosive chemicals in bags at public venues. Their inexpensive detection system needs a Wi-Fi device with two to three antennas and can be integrated into existing Wi-Fi networks. The system analyzes what occurs when wireless signals penetrate and bounce off objects and materials. Detection is 99% accurate for dangerous objects, 98% accurate for metal, and 95% accurate for liquid.

Rutgers's Yingying Chen says the accuracy rate tops 95% for most backpacks, falling to about 90% when objects inside bags are wrapped. She says the next phase of the project will involve boosting the system's accuracy in identifying objects by imaging their shapes and calculating liquid volumes.
