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.
