    摘要： An improved structure for use in a sensor includes an electrically conductive sensing element that provides improved durability in corrosive environments (ethanol, gasoline, etc.). A substrate may be formed using either ceramic or an anodized carrier of aluminum. In either case, the substrate presents an electrically insulating surface layer on which an electrically conductive sensing element may be formed. The conductive element is formed by thick film aluminum ink printing the desired shape (and thickness) of the element on the substrate, then firing the resulting structure. Thereafter, the entire structure, now with aluminum conductive elements, is anodized in order to form a protective and electrically insulative coating of a desired thickness. Another structure includes a base element or trace comprising an alloy of silver and palladium. An aluminum trace overlays the base element, and is thereafter anodized throughout its thickness to provide a protective layer.
