Dielectrophoretic Actuation in a Microfluidic System with Coplanar Electrode Configuration

This paper presents the analysis of the motion characteristics of droplet transport induced by liquid dielectrophoresis (LDEP). Hereby, a novel fluidic system is demonstrated, which enables droplet transport across a planar surface using a coplanar electrode configuration with adjacent electrodes. The droplet displacement is analyzed by high-speed video imaging and digital image processing. It is demonstrated that droplet motion can be initiated through simplified electrode geometries and the experimental results provide deeper insights into LDEP driven droplet manipulation.
