Textured surfaces,
comprised of grooves filled with air, e.g.,
air-filled surfaces (AFS), or with liquid, e.g., liquid-filled surfaces
(LFS), significantly influence fluid flows and the related electrokinetic
streaming potential (<i>V</i><sub>s</sub>). Here, electroosmotic
mobility related tensorial effects on the <i>V</i><sub>s</sub> were experimentally investigated. A significant modulation of the <i>V</i><sub>s</sub>, as high as 100%, due to transverse pressure
gradients, was demonstrated. The study yields insights into understanding
geometrical effects in electrolyte flows with implications to the
establishment of local electric fields, energy generation, and biological
separations.
