Pressure would then be released on demand, for fluid flow to take place over the micro-channels. Skip to search form Skip to main content.

Two frequency ranges castellanox to the macroelectrode were identified to notably increase the bacterial coverage of the impedimetric sensor per unit time.

However, heterogeneous ionic conductivity fields in the presence of applied electric fields can, under certain conditions, generate an unstable flow field owing to electrokinetic instabilities EKI. When such media are fluidsa flow is produced. Journal of Micromechanics and Microengineering. Electrokinetic flows with conductivity gradients become unstable when the electroviscous stretching and folding of conductivity interfaces grows faster than the dissipative effect of molecular diffusion.

Electrokinesis has also been observed in biology, where it was found to cause physical damage to neurons by inciting movement in their membranes.

Numerical investigations of AC electrokinetic forces to enhance the rate of transport of reactants in a microchannel A. SmithAdrian R. From Wikipedia, the free encyclopedia. Electrohydrodynamics EHDalso known as electro-fluid-dynamics EFD electohydrodynamics electrokineticsis the study of the dynamics of electrically charged fluids.

Since these flows are characterized by low velocities and eelctrohydrodynamics length scales, the Reynolds number is below 0.

Electrohydroeynamics On a Chip: The high strength electric fields that are often used in separation systems can give rise to fluid motion, which in turn results in a viscous drag on the particle. Status of the theory, technology, and applications Numa CouniotLaurent A. A linear double-layer analysis In OctoberDr. This streaming potentialwater-flow phenomenon was discovered in by German physicist Georg Hermann Quincke.

The Lev-vection particle concentrator: Electrokinesis is of considerable practical importance in microfluidics[4] [5] [6] because it offers a way to manipulate and convey fluids in microsystems using only electric fields, with no moving parts.

Resonant dielectrophoresis and electrohydrodynamics for high-sensitivity impedance detection of whole-cell bacteria. References Publications referenced by this paper. Analytical model and numerical simulations This coupling results in an electric body force in the bulk liquid, outside the electric double layerthat can generate temporal, convective, and absolute electrohydrdoynamics instabilities. Transport in Microfluidic Devices. Electrode CMOS compatibility confers portability, miniaturization and affordability capabilities for building point-of-care Electrrohydrodynamics diagnostic tests in a lab-on-a-chip LoC.

At 63 MHz precisely, a resonance effect due to the device was found to dramatically increase the trapping of S.

Alan ElecrohydrodynamicsCharles G. See -kinesis for explanation and further uses of the -kinesis suffix.

In such case, the moving structure acts as an electric motor. Elul’s “Fixed charge in the cell membrane” These instabilities are caused by a coupling of electric fields and ionic conductivity gradients that results in an electric body force. Osmosis Drude particle Microelectrodes Test scaling. E, Statistical, nonlinear, and…. Larry Kostiuk and two graduate students castelalnos the University of Alberta discussed a method of hydrodynamic to electrical energy conversion castellanoa exploiting the electrohyxrodynamics electrokinetic properties of a liquid such as ordinary tap waterby pumping fluids through tiny micro-channels with a pressure difference.

A powered flow of medium within a shaped electrostatic field adds energy to the system which is picked up as a potential difference by electrodes. Citations Publications citing this paper.
