Electrochemical sensor compensated for relative humidity

An electrochemical gas sensor comprising:

• a first cell in communication with a second cell;
• each cell having:
• a substrate having a surface;
• an electrode being deposited on said surface, said electrode being both a counter and reference electrode;
• a first sensing electrode and a second sensing electrode, being spaced apart from one another and from said counter and reference electrode, being deposited on said surface;
• a first electrolytic material in contact with said first sensing electrode for carrying a flow of ions;
• a second electrolytic material in contact with said second sensing electrode for carrying a flow of ions;
• and
• additional electrolytic material in contact with the first sensing electrode and the second sensing electrode, wherein the additional electrolytic material acts as a conductive medium to carry ions from the second sensing electrode to the first sensing electrode.

An electrochemical gas sensor comprising:

• a substrate having a surface;
• three electrodes, said electrodes comprising a counter/reference electrode, a first sensing electrode and a second sensing electrode, said counter/reference electrode, said first sensing electrode and said second sensing electrode being spaced apart from one another and deposited on said surface of said substrate;
• a first electrolytic material having a first thickness and being in contact with said first sensing electrode for carrying a flow of ions;
• a second electrolytic material having a second thickness and being in contact with said second sensing electrode for carrying a flow of ions, said second thickness being less than said first thickness;
• and
• additional electrolytic material in contact with the three electrodes, wherein the additional electrolytic material acts as a conductive medium to carry ions from the second sensing electrode to the first sensing electrode.
