In the present study, a cross-sectional capacitance is measured in a microchannel with 12 multi-layered electrodes at upstream and downstream cross-section. Based on the cross-sectional capacitance measurement, the particle volume fraction is determined at two configuration areas of electrode pair; at horizontal and vertical pair. The particle volume fraction shows some increment 9.3% at electrode pair near the walls, whilst decreased 0.96% at center electrode pair from upstream to downstream cross-section. As position move from inlets to outlets area, the particles drift away from center streamlines to near walls and a number of particles migrations near the walls are clearly increased at outlet area.
