The disclosure provides a sensor including a sensor having an external surface and a cannula. The cannula comprises a substantially cylindrical wall encircling a lumen, at least one aperture and a distal end. The sensor is positioned within the lumen and the distal end of the cannula extends beyond the sensor. This configuration functions for example to stabilize chemical reactions associated with the sensor by creating a buffer zone between the sensor and the surrounding tissues at the site of implantation. In certain embodiments, the sensor can further comprise an accessory material in proximity to the external surface, wherein the accessory material modifies the biological response of a tissue that is in contact with the sensor. The sensor can also comprise anchors that keeps the sensor in contact with subcutaneous tissue of a subject upon insertion of the sensor into the body of the subject.

A single flex double-sided electrode useful in a continuous glucose monitoring sensor. In one example, a counter electrode is placed on the back-side of the flex and a work electrode is placed on the top-side of the sensor flex. The electrode is fabricated on physical vapor deposited metal deposited on a base substrate. Adhesion of the electrode to the base substrate is carefully controlled so that the electrode can be processed on the substrate and subsequently removed from the substrate after processing.

The invention disclosed herein includes electrode compositions formed from processes that sputter metal in a manner that produces pillar architectures. Embodiments of the invention can be used in analyte sensors having such electrode architectures as well as methods for making and using these sensor electrodes. A number of working embodiments of the invention are shown to be useful in amperometric glucose sensors worn by diabetic individuals. However, the metal pillar structures have wide ranging applicability and should increase surface area and decrease charge density for catalyst layers or electrodes used with sensing, power generation, recording, and stimulation, in vitro and/or in the body, or outside the body.
