In one aspect, the inventive concepts disclosed herein are directed to a sensor assembly which contains a first planar substrate and a second planar substrate which respectively support opposing sensor arrays and contains an integrated flow path extending between the first and second substrates. Sensor assembly contains a first planar substrate having a base layer, and a conductive layer formed on a first planar surface of the base layer. Base layer may be made from, for example, ceramic, polymer, foil, or any other type of material known to someone of ordinary skill in the art. Conductive layer contains at least at least two electrically isolated electrical contacts made, for example, using a thick film approach (e.g., screen printing, rotogravure, pad printing, stenciling conductive material such as carbon, Cu, Pt, Pd, Au, and/or Nanotubes, etc.) or a thin firm approach (e.g., by sputtering, thermal spraying, and/or cold spraying conductive material).
