Abstract :
This paper presents a new structure in order to reduce voltage in dielectrophoresis (DEP). DEP is one of the most popular techniques to separate microparticles which needs an electric field in microfluidic devices. In this design we bend the microchannel (L-shaped) to reduce applying voltage. Also we change the outlet channel size which effectively reduces voltage. In the old design, we needed 2.5 V to separate 3.5 um and 4 um in diameter particles. In the new design, we keep constant all the effective parameters and bend the middle of the measuring microchannel and change the outlet microchannel size from 40 um to 50 um. We need 1.45 V to separate microparticles in the new conditions.
