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.

Abstract: The invention disclosed herein includes electrode compositions formed from processes that sputter metal in a manner that produces pillar architectures. Embodiments of the invention can be used in analyte sensors having such electrode architectures as well as methods for making and using these sensor electrodes. A number of working embodiments of the invention are shown to be useful in amperometric glucose sensors worn by diabetic individuals. However, the metal pillar structures have wide ranging applicability and should increase surface area and decrease charge density for catalyst layers or electrodes used with sensing, power generation, recording, and stimulation, in vitro and/or in the body, or outside the body.
