Smell Camera Snapshots Scents For the Future
An anonymous reader writes "Designer Amy Radcliffe has created an 'analog odor camera' that can be used to recreate a smell. From the article: 'When a smell source is placed under the device's glass cone, a pump extracts the smell via a plastic tube. After being drawn to Madeleine's main unit, the smell goes through a resin trap which absorbs the particles so molecular information can be recorded. That data is expressed in a graph-like formula, which essentially contains a fingerprint of the smell. In a special lab, that formula can then be inscribed on a bronze disk to artificially reproduce the smell. The smell can also be recreated in small vials.'"
the reaction is to several proteins found in peanuts, something that "smells like peanuts" but not containing specific allergens would not trigger immune reaction.
