Dielectrophoresis is a phenomenon in which a force is exerted on a dielectric particle when it is subjected to a non-uniform electric field. In this research, we analyze dielectrophoretic (DEP) force using a geometry containing two electrodes, one with SiO2 and one without, with a gap between them. The relevant governing equations include the DEP force, the electrohydrodynamic and corresponding electrothermal forces, and the gravitational and buoyancy forces. The model is simulated using COMSOL Multiphysics® and the MEMS Module, where we examine the electrostatics, convection and conduction, and microfluidics of the system.
