Abstract
The present teachings relate to microfluidic valves and pumping systems, which may be suitable for controlling and facilitating liquid flow. Electrodes are disposed proximately to volumes containing a liquid. The liquid flow can be facilitated by electrowetting forces. Processes for controlling the flow of liquids, as well as for pumping liquids, are also disclosed.
