Abstract

------ 25/06/2019 ------ (OCR) page 1 of number 1 page invention summary. The invention addresses the process of fabricating a gas sensor assembly based on electrical and optical vapor detection. The sensors are suitable for applications in the measurement of vapors in the food and beverage industry. The invention was developed to be able to measure vapors and could provide no less than 12 data sets of response data, including four electro-gas sensor response data resulting from the material response. Four sensors are MWCNTs / Nile red, MWCNTs / MgTPP, MWCNTs / MnTPPCl and MWCNTs, and 12 datasets of optical sensor gas response data resulting from the material response of the thin film optical sensor 2. A layer of zinc oxide film that is doped with aluminum metal. And thin films of Nile Red dye mixtures and polystyrene-co-maleic acid copolymer isobutyl / methyl mix ester ( Nile red / PSE). The thin films of this optical sensor material exhibit a wide range of responses to light at different wavelengths. Thus it can provide a large amount of response information. This is very useful in improving the efficiency of odor classification analysis by various statistical methods. Another distinctive feature of the gas sensor assembly based on the detection of electrical and optical vapors is the transparent interdigitated sensor terminal made of a thin film of zinc oxide doped with aluminum metal. By adding one percent aluminum dioxide by weight. And the zinc oxide material used to make it is very inexpensive ------------ page 1 of the number 1 page.
