ELECTROKINETIC PUMP HAVING CAPACITIVE ELECTRODES |
摘要 |
An electrokinetic pump achieves high and low flow rates without producing significant gaseous byproducts and without significant evolution of the pump fluid. A first feature of the pump is that the electrodes in the pump are capacitive with a capacitance of at least 10−4 Farads/cm2. A second feature of the pump is that it is configured to maximize the potential across the porous dielectric material. The pump can have either or both features. |

1. An electrokinetic system, comprising:
an electrokinetic device including a pair of electrodes and a porous dielectric material between the electrodes, the pair of electrodes capable of having a voltage drop therebetween; a liquid in the elecktrokinetic device between the pair of electrodes; a power supply; and
a controller, the controller configured to: (a) apply a positive current from the power supply to the electrodes to charge the capacitance of the electrodes and to move the liquid through the porous dielectric material in a first direction; (b) reverse the current applied by the power supply to the electrodes prior to reaching a threshold voltage for a Faradaic process in the liquid; and (c) apply a negative current from the power supply to the electrodes to move the liquid through the porous dielectric material in a second direction that is opposite to the first directions. |
