▎ 摘　　要

NOVELTY - Multi-parameter integrated bionic odor sensory chip comprises multiple mutually independent graphene field-effect transistor (FET) sensors. Each graphene FET sensor comprises a silicon oxide substrate, a source electrode (3), a drain electrode (4), a graphene gate electrode, a source electrode lead (2), a drain electrode lead (6), a gate pole leads, olfactory receptor proteins and bonding pad (1). The source electrode, drain electrode and graphene gate electrode attached on the silicon oxide substrate. The graphene gate electrode is located between source electrode and drain electrode. The olfactory receptor protein is immobilized on the surface of graphene grid electrode. The olfactory receptor protein is used as graphene FET sensitive material of the sensor, and its conformation changes after combining with gas molecules. The chip has different response thermogram for different gases, and combined with pattern recognition algorithms, which can detect different types of gases. USE - The multi-parameter integrated bionic odor sensory chip is useful in odor detection (claimed). Can also be useful in the fields of air quality monitoring, food safety, hazardous product detection. ADVANTAGE - The chip has high throughput, small size, high integration and low energy consumption, changes gate current of the field effect transistor, normalizes current signal, constructs response maps of different gas molecules to form an odor database, and achieves high-dimensional detection and accurate identification of different odors. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparation method of bionic odor sensory chip based on multi-parameter integration; and using method of multi-parameter integrated bionic odor sensory chip in odor detection. DESCRIPTION OF DRAWING(S) - The drawing shows an overall schematic view of multi-parameter integrated bionic odor sensory chip. 1Bonding pad 2Source electrode lead 3Source electrode 4Drain electrode 5Gate graphene 6Drain electrode lead
