Electronic nose app soon in smartphones

  Could any one think of a electronic nose which can diagnose an illness by analysing a person’s breath.This application is going to be invented in London which  can easily detect any communicable diseases.It is easy to carry and doctors need not carry any type of instruments with them to detect disease.This is is just made for the smartphones and it is affordable.

  A scientist team  at the California Institute of Technology, led by professor Nate Lewis, is trialling the technology what they call “sensory vapour technology” which could detect odours like the human nose. The scientist are positively thinking that there will be no technical problems in the working  of the app to detect any type of odours.

   Team member Heather McCaig said: “A doctor could carry around their smartphone and have patients breathe into a little attachment and be able to tell they have a communicable disease like tuberculosis.If this app is released then the doctors can breath easy as the difficulty of taking the samples and sending it in to the labs for the research will be ended.This is a good news for the patients as the disease can be detected accurately, in a second  and the treatment can be started.

   The detection of the disease will go through a process which contains pushing a stream of air through a liquid, such as butanol, which results in bubbles that come up as a saturated vapour. This is then diluted and fed to a sensor chamber where the vapour is analysed and turned into raw data.
