Analyte sensors having temperature independent membranes

摘要

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.
