Abstract
An object of the present invention is to provide an artificial olfactory sensing system capable of sniffing out various odors highly sensitively. The artificial olfactory sensing system includes: plural sensor cells on a lipid membrane of each of which olfactory receptors have developed; and plural ion-sensitive field-effect transistors (ISFETs) that correspondingly exist to the sensor cells on a one-on-one basis. A response signal showing that each of the olfactory receptors of each of the sensor cells has recognized an odor molecule is converted into an electric signal by an ISFET corresponding to each of the sensor cells.
