Smell
gallery ibm 5 senses smell

Do you think you're coming down with a cold? In five years, you'll be able to breathe into your smartphone to find out.

IBM researchers are developing technology to analyze odors in people's breath that identify ailments, including liver and kidney disorders, asthma, diabetes and epilepsy. By determining which odors and molecules in a person's breath are associated with each disease, computers of the future will be able to make an instant analysis for problems that today could be misdiagnosed or go undetected by a doctor.

Computers will also be able to detect harmful bacteria that cause Staph infections in hospitals just by smelling the surroundings.

In a more rudimentary form, computers are smelling things now: Agricultural sensors smell soil to determine crop conditions, sensors in museums determine which gas levels are ideal to preserve paintings, and city sanitation departments use computers that can smell garbage and pollution to alert workers when conditions are getting dangerous.
