1. A corrosion sensor comprising:
a substrate; and
a patterned conductive layer provided on the substrate,
wherein the patterned conductive layer defines: a common terminal; a set of terminals, including a first terminal and a second terminal; a set of sensing elements, including a first sensing element and a second sensing element; and a set of conductive regions, including a first conductive region,
wherein respective sensing elements of the set thereof are electrically coupled to the common terminal and to respective terminals of the set thereof, such that the respective terminals of the set thereof are specific to the respective sensing elements of the set thereof,
wherein respective conductive regions of the set thereof are disposed between and electrically isolated from respective sensing elements of the set thereof,
wherein the first conductive region comprises a first set of conductive subregions, including a first conductive subregion and a second conductive subregion, and
wherein respective conductive subregions of the set thereof are mutually electrically isolated.
