Low power, lightweight vapor sensing using arrays of conducting polymer composite chemically-sensitive resistors.

摘要: Arrays of broadly responsive vapor detectors can be used to detect, identify, and quantify vapors mixtures. One implementation this strategy involves the use arrays chemically-sensitive resistors made from conducting polymer composites. Sorption an analyte into composite detector leads swelling film material. The is in turn transduced a change electrical resistance because films consist polymers filled with particles such as carbon black. differential sorption, thus swelling, each array produces unique pattern for different interest, Pattern recognition algorithms are then analyze multivariate data arising responses array. Chiral provide detection presence certain chiral organic analytes. Aspects spaceflight qualification deployment array, along its performance analytes interest manned life support applications, reviewed summarized article.
