ARTIFICIAL OLFACTORY SENSING SYSTEM AND MANUFACTURING METHOD THEREFOR

摘要

To improve the performance of an artificial olfactory sensing system.SOLUTION: An artificial olfactory sensing system comprises a semiconductor device SD1 including a transistor, and a sensor unit S11 including a sensor cell C11 where an olfactory receptor OR is expressed in a lipid membrane LB, with a proton adsorption film PAF1 formed on a gate electrode GE included in the transistor and a physiological solution RS arranged on the proton adsorption film PAF1. The sensor cell C11 is arranged in the physiological solution RS, and a proton Pa is adsorbed to the proton adsorption film PAF1. When the olfactory receptor OR recognizes an odor molecule OM, positive ions in the physiological solution RS flow into the sensor cell C11 from an ion channel provided in the olfactory receptor OR, resulting in that the proton Pa dissociates from the proton adsorption film PAF1 into the physiological solution RS and the potential of the gate electrode GE changes.SELECTED DRAWING: Figure 5
