Electronic nose that captures odour..

  Now, a camera that ‘clicks’ smells..

 

             Researchers in the UK have developed a camera that can capture the scent of your memories, recording smells instead of images. The gadget, called Madeleine, is the invention of designer Amy Radcliffe, who set out to bring a more meaningful sensory dimension to storing our favourite memories, the Guardian reported. "The sense of smell has a direct link to emotional memory . It is the sense we react to most instinctively, and the furthest away from being stored or replicated digitally," Radcliffe told the newspaper.
In order to use the camera, a person needs to place a funnel attached to the camera over the object or environment they wish to capture. Then a pump sucks the air across an odour trap made of Tenax — a porous polymer resin which adsorbs the particles that make up the smell. The working prototype can take anything from a few minutes to capture the ravishing scent of fresh strawberries , to around 24 hours to store the more subtle aroma of an atmosphere. "It's like a huge electric nose. It processes the particles and produces a graph-like formula that makes up the smell. From this formula you can artificially recreate the precise odour," she said.
