Development of a Multi-Stage Electroosmotic Flow Pump Using Liquid Metal Electrodes
Injection of liquid metal into a polydimethylsiloxane (PDMS) channel can provide a simple, cheap, and fast method to fabricate a noncontact electrode for micro electroosmotic flow (EOF) pumps. In this study, a multi-stage EOF pump using liquid metal noncontact electrodes was proposed and demonstrated for high-flow-velocity applications. To test the pumping performance of this EOF pump and measu...
متن کاملFabrication and electroosmotic flow measurements in micro- and nanofluidic channels
An easy method for fabricating microand nanofluidic channels, entirely made of a thermally grown silicon dioxide is presented. The nanochannels are up to 1-mm long and have widths and heights down to 200 nm, whereas the microfluidic channels are 20-lm wide and 4.8-lm high. The nanochannels are created at the interface of two silicon wafers. Their fabrication is based on the expansion of growing...
متن کامل-Implementation of lattice Boltzmann method to study mixing reduction in isothermal electroosmotic pump with hydrophobic walls
The aim of the present work is to analyze the accuracy and to extend the capability of lattice Boltzmann method in slip EOF; a phenomenon which was previously studied by molecular dynamics and less considered by LBM. At the present work, a numerical experiment on boundary conditions of slip velocity is performed and the proportionality of slip with shear stress in electroosmotic pump is proved....
متن کاملElectroosmotic shear flow in microchannels.
We generate and study electroosmotic shear flow in microchannels. By chemically or electrically modifying the surface potential of the channel walls a shear flow component with controllable velocity gradient can be added to the electroosmotic flow caused by double layer effects at the channel walls. Chemical modification is obtained by treating the channel wall with a cationic polymer. In case ...
