1. A multi-analyte electrochemical sensor, comprising:
a first conductive substrate being coupled to, and electrically isolated from, a second conductive substrate;
a first electrode trace being formed from the first conductive substrate, the first electrode trace including a plurality of first working electrode openings being formed in an A-side insulator;
a second electrode trace being formed from the first conductive substrate, the second electrode trace including a plurality of second working electrode openings being formed in the A-side insulator;
a first transport material covering the plurality of first working electrode openings;
a second transport material covering the plurality of second working electrode openings;
a third transport material covering the first transport material and the second transport material, the third transport material forming a barrier between the first transport material and the second transport material, and
a counter-reference electrode being formed on the second conductive substrate.
