Adaptive Finite Element Simulation of Steady State Currents at Microdisc Electrodes to a Guaranteed Accuracy

Theory and experiments of transport at channel microband electrodes under laminar flows. 2. Electrochemical regimes at double microband assemblies under steady state.

The development of any particular analytical or preparative applications using electrochemical techniques in microfluidic devices requires integration of microelectrodes. This involves detailed predictions for optimizing the design of devices and selecting the best hydrodynamic conditions. For this purpose, we undertook a series of works aimed at a precise investigation of mass transport near e...

Theoretical treatment and computer simulation of microelectrode arrays

New relations for and interrelations between the current responses of different microelectrode arrays are presented. Interdigitated microelectrode arrays (IDAs: alternating cathodes and anodes) and uniform microband electrode arrays (MEAs: only cathodes or anodes) are treated, and miniaturized systems with planar band electrodes or hemicylinder electrodes are discussed. A common basis was found...

Electrochemical Measurements with Interdigitated Array Microelectrodes

ing into widespread use for the trace determination of easily oxidizable and reducible organic and inorganic compounds, because it provides a rather easy procedure for direct and selective detection. Recently, microelectrodes have been receiving attention in this field (1,2). They offer higher sensitivity than macroelectrodes of conventional size, because an electroactive molecule can approach ...

Adaptive finite element methods in electrochemistry.

In this article, we review some of our previous work that considers the general problem of numerical simulation of the currents at microelectrodes using an adaptive finite element approach. Microelectrodes typically consist of an electrode embedded (or recessed) in an insulating material. For all such electrodes, numerical simulation is made difficult by the presence of a boundary singularity a...
