The Electronic Nose enose Technology

An electronic nose (e-nose) is a device that identifies the specific components of an odor and analyzes its chemical makeup to identify it. In a sense it mimics the human nose, but it has far greater sensitivity to smell and can trace scents at the nanoparticle level.

Electronic noses are not new. They have been around for several years. Electronic noses were originally used for quality control applications in

the food, beverage, and cosmetics industries. However, the e-nose is large and expensive to manufacture.

Current research is focused on making the e-nose smaller, less expensive, and more sensitive. The new and improved e-nose could be used to detect odors specific to diseases for medical diagnosis, the detection of pollutants, and gas leaks for environmental protection.
