Claim:
1. A sensor comprising: a first electrically non-conductive substrate having a sensing portion configured to be percutaneously inserted into a patient and an extracorporeal circuit mounting portion, the sensing portion including a sensor having at least one sensor electrode formed thereon in the form of at least a first electrically conductive trace, and the extracorporeal circuit mounting portion having at least one electrically conductive pad formed on one surface thereof, the at least one electrically conductive pad electrically connected to the at least one sensor electrode via at least a second electrically conductive trace formed on the sensing and circuit mounting portions of the first substrate, the sensor configured to produce a signal indicative of a condition of the patient, a second substrate having a first surface mounted to the one surface of the first substrate, the first surface of the second substrate defining thereon a first number of electrically conductive pads, the second substrate having a second surface, opposite the first surface, defining thereon a second number of electrically conductive pads, at least one of the first number of electrically conductive pads being aligned with the at least one electrically conductive pad defined on the one surface of the first substrate, the at least one of the first number of electrically conductive pads being electrically connected to at least one of the second number of electrically conductive pads, means for establishing electrical contact between the at least one electrically conductive pad defined on the one surface of the first substrate and the at least one of the first number of electrically conductive pads defined on the first surface of the second substrate, a third substrate having a first surface mounted to the second surface of the second substrate and defining thereon at least one electrical terminal, the at least one electrical terminal being aligned with the at least one of the second number of electrically conductive pads defined on the second surface of the second substrate, a first number of electrical components mounted to a second surface of the third substrate, opposite the first surface thereof, and electrically interconnected to form a sensor control circuit, the sensor control circuit being electrically connected to the at least one electrical terminal defined on the first surface of the third substrate, and means for establishing electrical contact between the at least one of the second number of electrically conductive pads defined on the second surface of the second substrate and the at least one electrical terminal defined on the first surface of the third substrate, the sensor being thereby electrically connected to the sensor control circuit.
