Wearable For Military Detects Toxic Gases, Warns Via Wireless App

A growing range of wearable monitors may help us lead stronger, smoother lives, but MIT's newest device is looking to save them--specifically, by alerting soldiers when toxic gases are around. Researchers from MIT's Swager Group developed the small chemical sensors to detect toxic gases in trace amounts using adapted carbon nanotubes, and are working to put this technology in wireless-friendly form for field use as soon as possible.
