Simulating a dog's sense of smell to collaborate with canines: Building artificial noses to sense threatening odors Surely you're aware of a dogs powerful sense of smell, and you might know that our noses pale in comparison, but have you ever wondered how strong a dogs nose really is? More importantly, wouldn't you like to experience that sense of smell for yourself? What if this supreme sense of olfaction could be replicated and implemented into industries where sensing smell is a top priority? This simulation, or biomimicry, could improve our technologies and even increase our overall security. The K-9 is one of natures best chemical detectors. To put it in perspective, these loyal companions' noses that are about 10,000 to 100,000 times more acute than ours. Even on the low end of this spectrum, this is the visual equivalent of seeing 3000 miles in any direction with clarity! [1] Photo: When a dog breathes in, the air separates into d...
