1. A method of fabricating an electrode for use in an analyte sensor, the method comprising:
- contacting an electrode with a sensing layer; and
eithercontacting the sensing layer with a first membrane having a negative temperature coefficient, and then contacting the first membrane with a second membrane having a positive temperature coefficient, orcontacting the sensing layer with a second membrane having a positive temperature coefficient, and then contacting the second membrane with a first membrane having a negative temperature coefficient,thereby forming a stacked membrane structure, wherein the stacked membrane structure has an analyte permeability that is substantially temperature independent.

Abstract
Embodiments of the present disclosure relate to analyte determining methods and devices (e.g., electrochemical analyte monitoring systems) that have a membrane structure with an analyte permeability that is substantially temperature independent. The devices also include a sensing layer disposed on a working electrode of in vivo analyte sensors, e.g., continuous and/or automatic in vivo monitoring using analyte sensors and/or test strips. Also provided are systems and methods of using the, for example electrochemical, analyte sensors in analyte monitoring.
