In this paper, we present the methods of the particle separation by employing DEP, TWEO and the inclined gravity. When particles are on a plane electrode, the particles do not experience the DEP force. Because the electric field at surface of the plane electrode is zero. Thus it is necessary to transport all particles from the entire chamber to the electrode gap, where the separation of the particles can be done. To cope with this problem, we create the "Bottle neck Fork-trace electrode (BF electrode) " to separation of all particles in a chamber. The BF electrode is possible to transport all particles from the entire chamber to the electrode gap by TWEO at first, and then separate them by DEP and the inclined gravity. Polystyrene beads, glass beads, yeast cells and barium titanate beads in NaCl solutions are separated by this electrode.
