Electrochemical NPKS sensor device
Description / Description
According to an aspect of the invention, there is provided an electrochemical ion
sensor for sensing a presence of at least one ion species in a solution. The
electrochemical sensor includes, for each of the at least one ion species:
? a solid-state electrolyte medium, doped with an organometallic material,
the organometallic material having an electrochemical affinity with the
ion species;
? a pair of electrodes electrically contacting the solid-state electrolyte
medium;
? an electrical circuit configured to drive the pair of electrodes with an AC
electrical excitation and to measure at least one parameter related to a
complex electrical impedance of the doped solid-state electrolyte
medium in response to the AC electrical excitation, said at least one
parameter being representative of the presence of the ion species in the
solution when the solid-state electrolyte medium is exposed to the
solution.
