Humans have been trying to harness the power of a dog's nose for a long time, but even the best electronic scent-detection devices, which try to emulate dog noses, aren't quite up to snuff. Matthew Staymates, a mechanical engineer and fluid dynamicist with the National Institute of Standards and Technology (NIST) was the lead author on a recently published paper that offers new insight into how a dog's nose works, and how it can be applied to modern detection equipment. Staymates used a Stratasys digital materials 3D printer, from the Connex series, to print out a replica of a female Labrador retriever's nose, and attached it to an electronic detector, to mimic how an actual dog smells.
