title: Oxygen fields induced by recessed and needle oxygen microelectrodes in homogeneous media.
abstract: Computer simulations of the operation of both the recessed and conically-shaped needle type microelectrodes were developed. The accurate portrayal of their geometries was greatly facilitated by the use of specialized three dimensional orthogonal coordinate systems with coordinate surfaces coincident with the geometry of the problem. From the simulations, calculations were made of the induced PO2 fields, oxygen sensitivities, stirring artifacts, measurement errors, and time constants.
