Electroosmotic micropump analysis for lab on chip water quality monitoring

In this work, a novel design of Electroosmotic micropump with low voltage for Lab on a Chip application is proposed and investigated using theoretical analysis and numerical simulations. The micropump is equipped with four microelectrodes which are embedded at the surface with 45° inclination nearby the inlet and outlet. Some microchannels are implanted through the micropump in purpose to attend a reasonable flow rate for Lab on a Chip application with low voltage. Theoretical analysis and numerical simulations are performed to predict the flow rate of the micropump and the microchannels effect on pumping efficiency. The effect of various microchannels dimension on the performance of the micropump in term of width and length is investigated. Good agreement is shown between the model results and.
