Electrohydrodynamics and dielectrophoresis in microsystems : scaling laws

Sonkusale PloS one Numerical investigations of AC electrokinetic forces to enhance the rate of transport of reactants in a microchannel A. Numa CouniotLaurent A. Modeling of dielectrophoresis in micro and nano systems Y Lin This coupling results in an electric body force in the bulk liquid, outside the electric double layerthat can generate temporal, convective, and absolute flow instabilities.

FrancisDenis Flandre Lab on a chip When such media are fluidsa flow is produced. Electrokinetic flows electorhydrodynamics conductivity gradients become unstable when the electroviscous stretching and folding of conductivity interfaces grows faster than the dissipative effect of molecular diffusion.

Peyrade PloS one However, heterogeneous ionic conductivity fields electrohyrrodynamics the presence of applied electric fields can, under certain conditions, generate an unstable flow field owing to electrokinetic instabilities EKI. Footer menu Conditions Contact Statistics.


Skip to search form Skip to main content. EKI’s can be leveraged for rapid mixing or can cause undesirable dispersion in sample injection, separation and stacking.

Journal of Micromechanics and Microengineering. Although the power generated from a single channel is extremely small, millions of parallel micro-channels can be used to increase the power output.

Retrieved from ” https: These instabilities are caused by a coupling of electric fields and ionic conductivity gradients that results in an electric body force. Elul’s “Fixed charge in the cell membrane” Observation of streamlines and numerical simulation.

Two electrouydrodynamics ranges applied to the macroelectrode were identified to notably increase the bacterial coverage of the impedimetric sensor per unit time. Electrokinesis has also been observed in biology, where it was found to cause physical damage to neurons by inciting electohydrodynamics in their membranes. 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.

From This Paper Figures, tables, and topics from this paper. The fluid flows in microfluidic and nanofluidic devices are often stable and strongly damped by viscous forces with Reynolds numbers of order unity or smaller. It can also refer to fictional superpowers to manipulate electricity. Brownian motion Electroconvulsive Therapy Image scaling Experiment. ManoharSameer R. This paper has highly influenced 11 other papers. Microfluidics and Miniaturization Electrohydrodynamics and dielectrophoresis in microsystems: Practical fields of interest of EHD are the common air ioniserelectrohydrodynamic thrusters and EHD cooling systems.


Electrode CMOS compatibility confers portability, miniaturization and affordability capabilities for building point-of-care PoC diagnostic tests in a lab-on-a-chip LoC. Views Read Edit View history. The electric field generates heat, leading to volume forces in the liquid. The dynamics and periodic morphology of electrokinetic instabilities are similar to other systems with Rayleigh—Taylor instabilities.

The ac electric fields induce movement of polarizable particles, a phenomenon known as dielectrophoresis. Since these flows are characterized by low velocities and small length scales, the Reynolds number is below 0. Brownian motion Search for additional papers on this topic.
