چكيده فارسي :
The present experimental study investigates the effect of the reservoir liquid volume on the dispensed droplet size in a microchannel based on electrowetting on dielectric (EWOD) technique. A crescent configuration is fabricated for the channel electrodes which provides a larger overlapping area. This leads to a higher electrowetting force between the adjacent electrodes which improves the droplet movement. In addition, special featured reservoir electrodes are patterned to facilitate the droplet dispensing. In order to examine the effect of the reservoir liquid volume on the dispensed droplet size, several experiments are performed. The dispensed droplets obtained in the experiments are in the range of 80-370 Nano litter. The channel dimensions, the size of the reservoir electrodes and the channel electrodes are fixed. Increasing the reservoir liquid volume leads to a smaller dispensed droplet.
