In these designs, air flows continuously through or over the odor source and is then transported via tubing to the subject. Vacuum pressure plays an important role in a continuous flow olfactometer, where it is utilized both to switch between odorized air flow and control flow and to evacuate odors, often just below the subject’s nose. The [4]
The more commonly used sensors for electronic noses include metal–oxide–semiconductor (MOS) devices – metal–oxide–semiconductor sensors contain a metal oxide coating with an electrical resistance that changes in the presence of a target gas. The presence of the target gas can be inferred by measuring the change in the resistance of ...
Machine olfaction is the automated simulation of the sense of smell. An emerging application in modern engineering, it involves the use of robots or other automated systems to analyze air-borne chemicals. Such an apparatus is often called an electronic nose or e-nose.
The olfactory system, is the sensory system used for the sense of smell (olfaction). Olfaction is one of the special senses directly associated with specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system.
When you breathe, air flows smoothly in and out of your nose, Ramakrishnan says. But when you sneeze, you expel air and change up that flow, forcing odorous particles in your nose or throat upward ...
