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.

First claim

What is claimed is:

1. A valving system comprising:
a first channel fluidly coupled to a first reservoir;
a second channel fluidly coupled to said first channel, said second channel having a first volume;
a first fluid obstruction included in the first volume,
wherein the first fluidic obstruction is configured to move to a first position and a second position in the first volume,
wherein the first fluidic objection is configured to block the second channel to prevent fluid…
