Abstract: Analyte sensors and methods for fabricating analyte sensors in a roll-to-roll process are provided. In an exemplary embodiment, a method includes providing a roll of a polyester substrate having a first side coated with a layer of platinum, wherein the platinum is in direct contact with the polyester substrate; patterning the layer of platinum to form electrodes; punching the polyester substrate to form ribbons, wherein each ribbon is connected to a remaining polyester substrate web by a tab, and wherein each sensor includes an electrode; after punching the polyester substrate to form ribbons, depositing an enzyme layer over the portions of the working electrodes and coating the working electrodes with a glucose limiting membrane; after depositing the enzyme layer over the portions of the working electrodes and coating the working electrodes with a glucose limiting membrane, singulating the individual sensors by completely separating each individual sensor from the polyester substrate.

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 from a 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.
