Abstract

An electrochemical cell having an auxiliary area that contains a redox species on a working electrode. The auxiliary area provides a low resistance current path between the working electrode and a pseudo reference/counter electrode. The auxiliary area is an integral part of the working electrode and allows an enhanced current to flow. The enhanced current adds to the measurement signal. This reduces non-monotonic current decay, which can lead to erroneous analyte measurements.
