Patent ID: 8728288

Claim:
A sensor assembly comprising: a first electronic wiring substrate having a first surface and a second surface and at least two analyte sensors formed on the first surface thereof, the at least two analyte sensors being connected with electrical contact points, a second electronic wiring substrate having a first surface and a second surface and at least two analyte sensors formed on the first surface thereof, the at least two analyte sensors being connected with electrical contact points, and a spacer having a through-going recess with a first opening and a second opening, wherein the first substrate, the second substrate and the spacer are arranged in a layered structure, where the first surface of the first substrate closes the first opening of the spacer and the first surface of the second substrate closes the second opening of the spacer, thereby forming a measuring cell in which all the analyte sensors on the first surface of the first substrate face the measuring cell through the first opening of the spacer and wherein all the analyte sensors on the first surface of the second substrate face the measuring cell through the second opening of the spacer, the measuring cell having a shape allowing fluid flow through the measuring cell to be substantially linear.
