Patent ID: 7232511

Claim:
A solid state agent sensor, comprising: a plurality of sub-micron sized inert noble metal electrodes formed on a silicon wafer, the electrodes for detecting at least one agent of interest; circuitry coupled to the plurality of electrodes for generating a biasing voltage for producing the biasing voltage to at least one electrode of the plurality of electrodes; and a membrane comprising an electrolyte solution formed within a polymer film to cover the plurality of electrodes for passing the at least one agent of interest to at least a portion of the plurality of electrodes wherein the solid state agent sensor is operable to generate at least one voltage to detect at least one agent of interest, wherein, the electrolyte solution of the membrane covering the plurality of electrodes comprises non-aqueous electrolytes, a stable salt, a polymer matrix materials, fumed silica particles and hydrophobic trimethylsilyl surface groups.
