Abstract
a substrate configured to be positioned in the presence of a fluid; a first electrode comprising a conductive film disposed on the substrate; and a second electrode comprising the conductive film disposed on the substrate and spaced from the first electrode. The device may further include a current measurement circuit configured to: apply a voltage between the first electrode and the second electrode, wherein the voltage is in an electrochemical active range of the conductive film such that a portion of the conductive film dissolves into the fluid; and transmit, to a processor, a signal indicating a current measurement of an electrical current flowing through the fluid including the dissolved portion of the conductive film.
