Abstract:
1. A corrosion sensor comprising: an insulating substrate; a thin film of a first metallic material formed on the substrate, the thin film constructed and arranged in a ladder-like configuration including a plurality rung-like features; an array of separate areas comprising a second metallic material, positioned on the plurality of rung-like features; a plurality of electrical terminals defined by the thin film for monitoring electrical resistance of the thin film; and a plurality of resistive tracks defined by the rung-like features of the thin film, at least portions of the plurality of resistive tracks providing a plurality of separate electrical pathways between the electrical terminals, wherein the separate areas comprising the second metallic material are provided at surfaces of the portions of the plurality of resistive tracks that provide the plurality of separate electrical pathways for enhancing a rate of galvanic corrosion of the thin film.
