Patent ID: 7527821

Claim:
A method for fabricating an olfactory sensor on a substrate having a pair of electrodes, said method comprising: a) depositing at least one conducting material as a first layer onto said substrate having a pair of electrodes, the first layer being capable of sensing a chemical analyte that contacts the first layer; b) depositing at least one non-conductive or insulating film that is capable of absorbing the chemical analyte that is provided thereon as a second layer, onto said first layer of conducting material, thereby fabricating said sensor; and c) post-processing said second layer after depositing upon said first layer of conducting material, in order to burn-in the olfactory sensor, wherein said olfactory sensor is comprised of at least one sensor composition, and wherein the chemical analyte is absorbed within the second layer so as to make contact with the first layer; and wherein the post-processing comprises: exposing the second layer to either a non-polar substance or a polar substance, wherein the exposing step is performed in cycles over a predetermined time period.
