摘要

Dielectrophoresis (DEP) is a phenomenon in which force exerted on a dielectric particle when it is subjected to a non-uniform electric field. There are many applications of dielectrophoresis and one of them is the separation of particles. In this paper, castellated and straight electrodes are being introduced for negative dep filter of an artificial kidney. In order to avoid the filters from clogging, negative dep will take part to repel the particles. Thus, a simulation by using COMSOL Multiphysics had been done to compare the electrical performances of electrodes. The intensities of electric field were stimulated on the planar electrodes from top to bottom and left to right. Electrodes are made of aluminum and both have thickness of 50um. Distance between the castellated electrodes are 100μm while the straight electrodes are 300μm. Three graph of electric field vs. length had been compared. The first comparison shows that both designs have similar flow of electric field. The second graphs show that castellated electrodes have higher electric field, 27.14kV/m and third comparison shows a cluster increase for castellated electrodes and uniform increase for straight electrodes. Final result shows that castellated electrodes are intended to use for artificial kidney.
