Abstract
Provided is an electrode-based pump having source of a pumped fluid, a conduit channel of capillary dimensions connected via a first end to the pumped fluid source and having an outlet at a second end, a piston channel with a first end that intersects the conduit channel, wherein the piston channel allows for periodic inward and outward movement of a piston plug of liquid, two or more electrodes inserted into the piston channel which define an electrode-based pump, wherein the electrode-based pump can be operated to move the piston plug of liquid inward and outward.
Claims17
An electrode-based pumping system comprising:
- a source of a pumped fluid;
- a conduit channel of capillary dimensions connected via a first end to the pumped fluid source and having an outlet at a second end;
- a piston channel with a first end that intersects the conduit channel, wherein the piston channel is shaped and configured to allow for periodic inward and outward movement of a piston plug of liquid;
- two or more electrodes inserted into the piston channel to form an electrode-based pump;
- and
- electrical components adapted to operate the electrode-based pump to move the piston plug of liquid inward and outward by cycling stroke action.
