Abstract :
This paper presents two types of electrowetting principles - regular electrowetting (EW) and electrowetting on dielectric (EWOD), applied for microactuation and correspondingly designed test devices for addressable micro liquid handling. The devices demonstrated sequential microactuation of liquid on electrodes with (EWOD) or without (EW) hydrophobic coating on them.
