GAS MULTI-SENSOR BASED ON ORGANIC FIELD TRANSISTORS (OPTIONS) AND DEVICE FOR ANALYSIS OF MULTI-COMPONENT GAS MIXTURE OF THE “ELECTRON NOSE” TYPE ON ITS BASIS Russian patent published in 2019 - IPC G01N27/414 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement technology, in particular, to gas analysis sensors – chemical sensors, designed to analyze the composition of gas mixtures, detect and quantify toxic chemical gaseous compounds in the environment. Gas multi-sensor includes an array of N organic field-effect transistors, each includes at least one electrode – a drain, a source – separated by a layer of organic semiconductor, electrode “gate”, dielectric layer and additional receptor layer based on metalloporphyrin of a certain chemical formula, completely or partially covering the organic semiconductor layer in the structure of the N organic field effect transistor, at that each of the N organic field-effect transistors in the array differs from other organic field-effect transistors in the array by the chemical structure of the receptor layer.

EFFECT: reduction of the lower threshold for detecting an electronic nose device based on chemisorption sensors.
