Abstract

The possible chemical crosstalk between electrodes in microfabricated voltammetric oxygen sensors has been studied with an interdigitated electrode assembly. Experimental results show that significant amounts of hydrogen peroxide can be produced at the Au or Pt cathode and transferred to the surface of nearby counter and reference electrodes. Such chemical crosstalk may not only distort the sensing signal, but also affects the stability of the gold anode and the Ag/AgCl reference electrode.
