Abstract
A microfluidic system includes an electrowetting on dielectric (EWOD) device comprising an array of elements that are actuatable for manipulation of a liquid droplet within the EWOD device. The system has a pattern generator that generates an actuation pattern for actuating a portion of the elements in the array of elements, and a signal generator that generates voltage signals for actuating elements in the array of elements in accordance with the actuation pattern. The pattern generator generates an actuation pattern in which voltage signals applied to elements in at least part of a region at or adjacent to a contact line of the droplet are different from voltage signals applied to elements that are not in the part of the region at or adjacent to the contact line. The system further may include a sensor for sensing the droplet contact line constituting a boundary of the liquid droplet.
