1. A sensor array for concurrently testing a first analyte and a second analyte, comprising:
an inlet;
an outlet;
a flow path configured to provide fluid from the inlet to the outlet, the flow path having a first sensing area to test the first analyte and a second sensing area to test the second analyte, the flow path defined by:
a first dielectric layer positioned on a first conductive layer, the first conductive layer having a first electrical contact electrically isolated from a second electrical contact such that the first sensing area is positioned adjacent to the first electrical contact and the second sensing area is positioned adjacent to the second electrical contact; and,
a second dielectric layer positioned on a second conductive layer, the second conductive layer having a third electrical contact positioned in an opposing orientation relative to the first electrical contact and a fourth electrical contact positioned in an opposing orientation relative to the second electrical contact such that the flow path passes between the first and third electrical contacts, and between the second and fourth electrical contacts;
wherein the flow path is configured to allow fluid to contact conductive material of the first electrical contact of the first sensing area and the second electrical contact second sensing area.
