1-20. (canceled)
A sensor for measuring an analyte concentration in a host, the sensor comprising:
- an elongated body configured to be implanted at least in part in a host, wherein the elongated body comprises:
- a substrate;
- a first layer covering at least a portion of the substrate, wherein the first layer comprises a first conductive material, wherein a portion of the first layer comprises a first electroactive surface;
- a second layer covering at least a portion of the first layer, wherein the second layer comprises an insulating material;
- a third layer covering at least a portion of the second layer, wherein the third layer comprises a second conductive material, wherein a portion of the second layer comprises a second electroactive surface;
- and
- a fourth layer covering at least a portion of the third layer, wherein the fourth layer comprise an insulating material;
- wherein the first electroactive surface and the second electroactive surface are separated along a longitudinal axis of the elongated body by at least a portion of the fourth layer.
