One of the common approaches for separating the micro-particles is the utilisation of dielectrophoresis (DEP) force. In the present study, a channel structure is introduced in which the controllable electric field is imposed by the use of various voltages to the parallel electrodes in order to finally move the different particles in two opposite sides of the channel. The simulation results reveal that the channel is characterised by the imposition of nearly constant DEP forces in the whole channel, which is the innovation of this work. The samples used for separation are Latex particles with 216 and 557nm in diameter.
