Abstract

Although the impinging dynamics of droplets on solid surfaces has been extensively studied, a complete study on the impact of impinging droplets on direct current electrowetting on dielectric (DC-EWOD) substrates with different configurations of electrodes and voltages is found limited. In order to investigate the dielectric performance and dynamics of EWOD with different voltages, experiments are performed on DC-EWOD. Parametric studies involving droplet diameter, droplet height, applied voltage, electrode spacing, etc., are studied in this work. At a Weber number of 20.02, jetting is inhibited by the application of direct current to the EWOD chip and the droplet shift to one side, and the magnitude of voltages shows a dominant effect on this phenomenon.
