Artificial olfactory system and an application thereof

The present invention relates to an artificial olfactory system ( 100 ), comprising of an inlet ( 101 ); a gas chamber ( 110 ) having a detector means, connected to a data acquisition system ( 104 ); a heater ( 112 ) and a plurality of fans ( 115 ); a humidity absorber ( 111 ); an outlet ( 102 ); a vacuum pump ( 103 ); characterized by the detector means having a plurality of sensors ( 121 ) in each of a plurality of clusters ( 120 ), wherein the plurality of sensors ( 121 ) in each of the plurality of clusters ( 120 ) comprises identical sensors capable of responding to a particular gas or vapor. The present invention also relates to a method for detecting a gas or a vapor from the artificial olfactory system ( 100 ), comprising the step of exposing the gas or vapor to the plurality of sensors ( 121 ) to produce a plurality of output signals from the plurality of sensors ( 121 ); transferring the plurality of output signals to the data acquisition system ( 104 ); extracting median data from the plurality of output signals; applying a principal component analysis (PCA), neural network, and least square regression analysis on the median data from all of the plurality of clusters ( 120 ).
