Graphical abstractDisplay Omitted Highlights?AC electroosmosis is used for pumping and mixing. ? A configurable asymmetry system is used in the pumping arrays. ? Both two-dimensional and three-dimensional designs are investigated. ? The designs are evaluated using numerical simulation. ? It is found that significant pumping and mixing can be achieved. In this paper configurable AC electroosmotic array devices are investigated for the purpose of combined pumping and mixing in microcapillaries. The method relies on grouping similar electrodes together in terms of applied voltage, in order to create configurable asymmetries in periodic electrode arrays. Novel designs and excitation patterns are examined for the electrode arrays and the results are evaluated in both absolute and relative terms compared to previously proposed array patterns.
