This study is focused on electroosmetic micromixer and the effects of driving force are investigated in the sense of different mixing channel width schemes. Two pairs of electrodes are mounted on the sidewalls of mixing channel to provide the required electric field. Various Numerical simulations are performed to assess the fluid flow in the presence of the electrokinetic driving force. Throughout...
This paper presents a microfluidic chip with arc-shape electrodes array (ASEA) for separation of different-size particles/Cells based on negative dielectrophoresis (nDEP). The purpose of ASEA is to generate the dielectrophoretic force perpendicular to the microchannel direction within the gap between each pairs of arc-shape electrodes. The DEP chip consisted of two regions of ASEA; first ASEA was...
Fluid flow generated by ac signals in a point-plane microsytem is studied. KCl aqueous solutions are used and fluid flow is observed for frequencies ranging from 100 Hz up to 1 MHz or 20 MHz depending on the electrolyte conductivity. Possible mechanisms for the explanation of the observed fluid flow are exposed.
