Claim 11:
12. The system of claim 11, wherein the first sensing device is a first electrochemical cell and wherein the first electrical characteristic of the first sensing device is monitored by determining a first voltage change at a first layer exposed to the first solution, wherein the first voltage change is with respect to a voltage at a first reference electrode also exposed to the first solution and the first layer covers a first working electrode of the first electrochemical cell; and wherein the second sensing device is a second electrochemical cell and wherein the second electrical characteristic of the second sensing device is monitored by determining a second voltage change at a second layer exposed to the second solution, wherein the second voltage change is with respect to a voltage at a second reference electrode also exposed to the second solution and the second layer covers a second working of the second electrochemical cell.
