  1. ELECTRONIC NOSE

  2. What is it? • Electronic Nose- A device that samples the specific components of an odor and analyzes its chemical makeup for identification • Consists of an array of electronic sensors used for chemical detection and a neural network mechanism used for pattern recognition

  3. How much does it cost? • Currently the electronic nose costs any where from $5,000 to $100,000 • Prices are projected to fall by 2020 to be affordable to most consumers

  4. PRESENT USES • Plant Disease Diagnosis • Electronic noses are being used in greenhouses to detect whether or not plants have been damaged. • Can determine whether or not a plant has physical damage or even if it is covered with insects. • When applied on a larger scale farmers will save money by finding early problems within the crops that could destroy their yields. • This allows for us to lessen the amount of pesticides being used on our crops.

  5. PRESENT USES (cont.) • Environmental Monitoring • Electronic noses are being used to monitor potentially harmful chemicals in water supplies. • Also used to help determine whether or not waste is radioactive or toxic to humans without putting anyone in harms way. • Can monitor air pollution at its source such as the top of power plant stacks. • Can be linked to one easy to use central database so information from multiple areas around the world can be monitored at once.

  6. PRESENT USES (cont.) • Medicine • The electronic nose had aided in the diagnosis of diseases due to the gas sensor technology. • The electronic nose can be used to detect the infection of microorganisms. These microorganisms produce a change on the smell of a person. • Odors in the breath can be indicative of gastrointestinal problems, sinus problems, infections, diabetes, and liver problems. Infected wounds and tissues emit distinctive odors that can be detected by an electronic nose. Odors coming from body fluids can indicate liver and bladder problems. • In 2009, the electronic nose was able to detect lung cancer from a person’s breath due to the detection of VOCs (volatile organic compounds). • Using nanotechnology, researchers found that specific VOCs in the breath of lung cancer patients arise from a metabolic pathway in tumor cells.

  7. FUTURE USES • In the medical field it may detect • Dangerous and harmful bacteria • Early signs of heart transplant rejection • Tuberculosis • In Law enforcement and security it may detect • Odorless chemicals or drugs which would make this ideal for use in the police force • Drug odors • It could also be used for bomb detection in airports

  8. FUTURE USES (cont.) • In retail/food services pplications of electronic noses in the food industry include • quality assessment in food production • inspection of food quality by odor • Refrigerator that knows when milk has gone bad • control of food cooking processes • inspection of fish • monitoring the fermentation process • monitoring food and beverage odors • grading whiskey • In homes it may detect • Dangerous gasses

  9. Examples of Future Electronic Nose inventions • Meat packages that flag spoilage • Mailboxes that check mail for bombs and/or traces of anthrax • Barroom coasters that double as Breathalyzers • Bumper stickers that monitor car emissions
