A method for manufacturing a corrosion sensor includes applying a first layer of non-conductive material to a substrate, writing a conductive material at discrete locations on the non-conductive material, and writing the conductive material at discrete locations on the previously written conductive material. The method further includes applying a second layer of non-conductive material over the conductive material and machining at least a portion of the second layer of non-conductive material to expose at least a portion of the conductive material.
