Artificial Dog Nose

Caption

Matt Staymates, a mechanical engineer at the National Institute of Standards and Technology (NIST), uses a schlieren imaging system to visualize the flow of vapors into an explosives detection device fitted with an artificial dog nose that mimics the "active sniffing" of a dog. The artificial dog nose, which was developed by Staymates and colleagues at NIST, the Massachusetts Institute of Technology Lincoln Laboratory, and the U.S. Food and Drug Administration, can improve trace chemical detection as much as 16-fold. © Robert Rathe
