Low power electrically-driven microfluidic pumping/delivery device

摘要

An electrically-actuated microfluidic device for fluid delivery and pumping is described. The micropumping device is configured as a capillary tube containing immiscible electrolyte liquids that are subjected to an alternating electrical voltage. The electrical voltage causes the boundary between the two liquids to change its surface tension in a way that provides a pumping action. The micropump requires only a few volts and milliwatts in order to operate.
