EWOD in Coplanar Electrode Configurations

This paper deals with ElectroWetting-On-Dielectric using AC voltage (AC EWOD) in both open and closed configuration. The open configuration is more convenient for fundamental studies and observations of electrowetting associated phenomena whereas the closed configuration is particularly adapted for practical use in a Digital lab-on-chips (DLC). Software developed for the study of electrowetting and droplet oscillations in coplanar electrode configuration are presented. Particular features of electrowetting are outlighted. Droplet oscillations and hydrodynamic induced flows in open coplanar configuration are considered and applications for DLC are illustrated in closed configuration.© 2010 ASME
