    Abstract

    We discuss the technological approaches to development of new single-electrode gas sensor based on Ti wire, up to 100 μm thick, which is functionalized via anodization to form the oxide nanoporous layer consisting of nanotubes at the surface. We show that proper optimization of anodization process results in mechanically stable structure which could serve as a gas sensor. The application of electrical power, up to 0,3 W, activates the chemiresistive effect in the wires, primarily in the oxide layers, as suggested. The preliminary tests show that the sensor could efficiently detect alcohol vapors. The gas discrimination could be achieved by combining few such sensors into array and processing the vector array signal by pattern recognition algorithms.
