▎ 摘　　要

NOVELTY - A nano-bionic flexible planar sensor is prepared by selecting nitrocellulose as a flexible substrate film, and depositing 6 nano-chromogenic materials on the surface of the substrate film to form 3x 2 sensor array. The nano-chromogenic materials are perovskite, titanium dioxide-coated ninhydrin, tungsten trioxide, spinel nickel cobaltite nanoflowers, cerium-zirconium oxide porous nanosheet and gold-embedded reduced graphene oxide hydrogel reticulated nanocage. USE - Nano-bionic flexible planar sensor is used for detecting specificity of nitrogen-containing volatile in pork storage process (claimed). ADVANTAGE - The nano-bionic flexible planar sensor detects specificity of nitrogen-containing volatile in pork storage process using different forms of specific nano-composite color-developing materials, integrates data information extraction and algorithm deep mining, presents gas information in image colors, and facilitates information intelligent processing. DETAILED DESCRIPTION - A nano-bionic flexible planar sensor is prepared by selecting nitrocellulose as a flexible substrate film, and depositing 6 nano-chromogenic materials on the surface of the substrate film to form 3x 2 sensor array. The nano-chromogenic materials are perovskite, titanium dioxide-coated ninhydrin, tungsten trioxide, spinel nickel cobaltite nanoflowers, cerium-zirconium oxide (Ce0.94Zr0.06O2) porous nanosheet and gold-embedded reduced graphene oxide hydrogel reticulated nanocage. An INDEPENDENT CLAIM is included for detection of nitrogen-containing volatile specificity in pork storage process.
