    摘要： A sensor structure is disclosed comprising at least four planar layers subsuming at least one cavity housed but not contained by overlapping apertures through at least two of the planar layers, wherein the at least one cavity comprises a plurality of chambers, and wherein at least one chamber of the plurality of chambers is configured to be in fluid coupling with at least one other chamber. The plurality of chambers may be defined by overlapping apertures through a plurality of the planar layers. The plurality of chambers may include a Gas Chromatograph (GC) column. The planar layers may be flexible flat glass. The planar layers may be fused together. The layers may be made with apertures through the layers disposed in a desired pattern to define complex structures by the apertures overlapping between abutting layers when the layers are stacked. The planar layers may be configured to admit ultraviolet light.

    摘要： Metal oxide-based integrated chemical sensors using a hybrid polycrystalline gas-sensitive material to create a uniform and integrated sensory system. The sensor system provides the unique properties such as improved sensor sensitivity due to reduced thickness, improved selectivity for specific analyte detection in the ppb, faster time of response, decreased time of reset and decreased power consumption in comparison to existing sensor technologies. The present invention also provides novel, metal oxide-based chemical sensor platforms, a novel method of making metal oxide-based chemical sensors, platforms and/or integrated chemical sensors.
