Electrohydrodynamic Pumping in Microsystems

  • Chapter
Electrokinetics and Electrohydrodynamics in Microsystems

Part of the book series: CISM Courses and Lectures ((CISM,volume 530))

Abstract

The electrical manipulation of fluids in microsystems has many existing and potential applications. This chapter reviews five different ways of electrohydrodynamic actuation in microdevices. First, we describe the basic equations of Electrohydrodynamics in the microscale, providing some basic concepts of electrical conduction in liquids. We also deal with some basic fluid-mechanical aspects that are common for micropumps. Then, five different electrohydrodynamic micropumps are studied and compared: from those that employ forces in the liquid bulk to those that employ forces in the electrical double layer.

This work has been supported by the Spanish Government Ministry MEC (contract FIS2006-03645) and the Regional Government Junta de Andalucía (contract P09-FQM-4584).
