Abstract:
We calculate the potential energy of an electrowetting array for different shapes and sizes of interdigital edge structures. To understand the dynamic effects at the beginning of the droplet motion is crucial for the optimization of the electrode structures with respect to fast switching and tolerance against droplet volume.
