Design of ceiling electrode for cell separation using positive Dielectrophoresis and inclined gravity

Dielctrophoresis (DEP) is a movement of particles in medium by a force, which is generated in non-uniform electric fields. The Dielectrophoretic force (DEP force) depends on the geometry of an electrode. In this paper, the design and the simulation of the ceiling electrode to separate biological cells by using positive dielectrophoresis and inclined gravity are presented. The positive DEP force which is generated around the designed ceiling electrode is measured by inclined gravity.
