How humans detect smell?

Some special kind of neurons called olfactory sensory neurons are present inside our nose.Each olfactory neuron expresses one odor receptor.Microscopic molecules released by particles around us stimulates these receptors.When the odorous particles have been detected by the neurons they send a message to the brain.And the smell is being detected.

How an e-nose works?

An e-nose is an electronic nose and is used to detect the smell of various particles.It has three main units:

  1. A delivery system
  2. detection system
  3. computing system

Electronic noses have sensor arrays which react which volatile compounds.When the volatile compounds are adsorbed on the sensor arrays, there occurs a physical change in the sensor.The response is recorded by electronic interface transforming the signal into a digital value.

Most commonly used sensors for e-nose

  1. Metal Oxide Semiconductor(MOSFET)devices
  2. conducting polymers
  3. Quartz crystal
  4. Surface acoustic wave

The adsorption theory(developed by myself)

The adsorption theory states that "if an odorous particle remained in gaseous state,then it can be adsorbed and desorp effectively provided:

  1. The particle must reach at a minimum pressure on the adsorbent.
  2. The particle must stick quite firmly and should not lose its fragrance on elapsing time.
  3. It should not react with the adsorbent.
  4. It could be easily desorped"

Theory of adsorption of gases

How to produce cheap Perfume?

As the olfactory particles are adsorbed, it could be used to make perfume. Here natural particles are being adsorbed at a lower cost and dissolve it to the base liquid. A basic design of fragrance adsorbent has been made. According to the design, the olfactory particles are adsorbed via an inlet and adsorbed using adsorbent. After adsorbing certain amount of olfactory particles,the adsorbed particles could be re-adsorbed.
