Creating minuscule devices
that can mimic olfactory systems is nothing new
, but an international team of researchers are reportedly working to improve an existing design by basing it on metal oxide nanowires. Granted, the actual technology is a bit above our noses, er, heads, but according to Dr. Andrei Kolmakov, the team's aim was to "demonstrate the excellent performance of a practical device made by combining bottom-up fabricated SnO2 nanowires / nanobelts as sensing elements with a multi-electrode KAMINA [e-nose] platform." More specifically, these gurus decided to implement a "completely new morphology of the sensing layer" composed of tin oxide nanowires rather than the traditional thin-film sensing element. Not surprisingly, those working on perfecting the device are hoping to one day have it installed in areas where intelligent sensor systems are used, but we wouldn't overlook the possibility of finding these things embedded in shirts of the future for those paranoid about their freshness.
