    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.
