Abstract
The present disclosure provides an analyte sensor comprising a working electrode, a sensing layer disposed on at least a portion of the working electrode, and a hydrophilic polyurethane membrane overcoating at least the sensing layer, wherein the hydrophilic polyurethane is aliphatic, aromatic, or both aliphatic and aromatic. The hydrophilic polyurethane membrane limits the transport of mass to the sensing layer without the need to be crosslinked. With such membrane, the analyte sensor can provide consistent analyte measurements over a temperature range of about 22-42° C. The present disclosure is further related to a method of forming an analyte sensor comprising providing a working electrode, disposing a sensing layer on at least a portion of the working electrode, and coating at least the sensing layer with a hydrophilic polyurethane membrane, wherein the hydrophilic polyurethane is aliphatic, aromatic, or both aliphatic and aromatic.
