Abstract

Analyte sensors and methods for fabricating analyte sensors are provided. In an exemplary embodiment, a planar flexible analyte sensor includes a flexible base layer and a first electrode formed froma layer of sputtered platinum on the base layer. Also, the analyte sensor includes an insulating dielectric layer over the base layer, wherein the insulating dielectric layer leaves a portion of the first electrode exposed. Further, the analyte sensor includes an electrochemical sensing stack over the exposed portion of the first electrode, including a glucose oxidase layer over the layer of sputtered platinum and a glucose limiting membrane over the glucose oxidase layer.
