Abstract
An electrochemical sensor including a working electrode having an arrangement of pillars defining channels between the pillars. The channels increase confinement of a byproduct produced in an electrochemical reaction used during sensing of an analyte, so as to increase interaction of the byproduct with the working electrode. A number of working embodiments of the invention are shown to be useful in amperometric glucose sensors worn by diabetic individuals.
