Abstract

------June 25, 2019------(OCR) Page 1 of 1 Abstract of the Invention This invention describes the process of fabricating a gas sensor assembly that relies on electrical and optical vapor detection. This sensor assembly is suitable for applications in vapor measurement in the food and beverage industry. The invention was developed to be able to measure vapors and provide at least 12 response data sets. These consist of 4 response data sets from the electrical gas sensor, resulting from the responses of 4 types of sensor materials: MWCNTs/Nile red, MWCNTs/MgTPP, MWCNTs/MnTPPCl, and MWCNTs, and 12 response data sets from the optical gas sensor, resulting from the responses of an optical sensor material made from a two-layer thin film of zinc oxide film doped with aluminum metal. A thin film of Nile red (PSE) dye composite material and polystyrene-composite isobutyl/methylmixed ester polymer (PSE) exhibits a wide range of light responses across different wavelengths, providing a large amount of response data. This is highly beneficial for improving the efficiency of statistical odor analysis and classification. Another highlight of this gas sensor system, based on electrical and optical vapor detection, is the transparent interdigitated sensor electrode made from a thin film of zinc oxide doped with aluminum. The aluminum dioxide used is 1% by weight, and the zinc oxide material is relatively inexpensive. ------------ Page 1 of 1. Invention Summary. This invention describes the fabrication process of a gas sensor system based on electrical and optical vapor detection. This sensor system is suitable for applications in vapor detection in the food and beverage industry. The invention was developed to detect vapors and provide at least 12 response datasets. These include 4 response datasets from electrical gas sensors, resulting from the responses of 4 types of sensor materials: MWCNTs/Nile red, MWCNTs/MgTPP, MWCNTs/MnTPPCl, and MWCNTs; and 12 response datasets from optical gas sensors, resulting from the responses of optical sensor materials made from 2-layer thin films of zinc oxide film doped with aluminum and a thin film of Nile red dye composite and polystyrene-composite-maleic acid partial isobutyl/methylmixed ester polymer (Nile red/PSE). These optical sensor thin films exhibit a wide range of light responses across different wavelengths, thus providing a large number of response datasets. This is highly beneficial in improving the efficiency of statistical odor analysis and classification. Another advantage of this gas sensor system, based on electrical and optical vapor detection, is... The transparent interdigitated sensor electrode is made from a thin film of zinc oxide doped with aluminum metal, specifically 1% by weight of aluminum dioxide. The zinc oxide material used is relatively inexpensive.
