Transverse electrokinetic and microfluidic effects in micro-patterned channels: lubrication analysis for slab geometries

Soft Condensed Matter 2009-11-07 v1

Abstract

Off-diagonal (transverse) effects in micro-patterned geometries are predicted and analyzed within the general frame of linear response theory, relating applied presure gradient and electric field to flow and electric current. These effects could contribute to the design of pumps, mixers or flow detectors. Shape and charge density modulations are proposed as a means to obtain sizeable transverse effects, as demonstrated by focusing on simple geometries and using the lubrication approximation.
