3D-Printed Dog Nose Sniffs Out Explosives
Added Dec 2, 2016 | Rate View top rated
Researchers have looked to one of nature’s best chemical detectors - the dog - to help make today’s chemical detection devices better at sniffing out explosives and other contraband materials. 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 3D-printed dog nose, which was developed by Staymates and colleagues at NIST, MIT, and the U.S. FDA, can improve trace chemical detection as much as 16-fold.
