A new machine lets first responders find people trapped at disaster sites by detecting individual molecules of breath, sweat, and urine that float up through the concrete. Firefighters and other first responders rushing to collapsing buildings and disaster situations will soon have a new weapon in their arsenal, replacing dogs, cameras, and robots: a series of sensors that find individual molecules of sweat and spit coming from victims trapped under concrete, locating them by their emissions. The high-tech emergency solution, which was unveiled in a research paper for the actually existing Journal of Breath Research, was created by a joint European team that reconfigured a series of commercially available detectors to hunt for unique human emanations.
