Scaling down the biochemical analytical system has been an important topic of research recently. Minimizing the energy requirement for the microfluidic transportation is essential for the realization of a Lab-on-a-chip (LOC) that can perform the Point-of-Care Testing (POCT). In this work, modeling and analysis of a low voltage Electro-osmotic (EO) micropump applicable for the Bio-Microfluidic systems using COMSOL Multiphysics software package is presented. In the previously reported low voltage EO micropump (3), position of electrodes makes the fabrication process a tedious task. Here, we investigate the effects of placing the electrodes tangential to the microchannel since such designs can be easily fabricated using PDMS/glass fabrication process, and also comparing the effect of different electrode configurations on the pump performance. In addition, the effects of geometrical parameters of micropump on volumetric flow rate and velocity profiles are investigated.
