1. A sensor assembly, comprising:
a sensor chip, comprising:
an array of conductive elements supported on the sensor chip,
dispense chemistry disposed on at least one conductive element of the array of conductive elements, and
at least one contact pad disposed on the sensor chip and spaced apart from the array of conductive elements; and
a microfluidic cap coupled to the sensor chip so that the microfluidic cap and the sensor chip define a first cavity that is located between the microfluidic cap and the sensor chip, the microfluidic cap comprising an electrode coupled to the at least one contact pad of the sensor chip via a conductive adhesive, the conductive adhesive located within the first cavity, the microfluidic cap and the sensor chip define a second cavity that is located between the microfluidic cap and the sensor chip, the second cavity configured to receive a fluid sample, the electrode in electrical communication with the second cavity for measuring an impedance or capacitance of the fluid sample when the fluid sample is present within the second cavity, the measured impedance or capacitance based on an analyte present within the fluid sample.
