Abstract
A microfluidic device has a layer with a capillary break formed by a capillary sluice. The capillary sluice has a lower surface and an upper surface. A first electrode is disposed on the lower surface. The first electrode is coupled to the voltage source. A second electrode spaced a predetermined distance from the first electrode is coupled to the voltage source. A controller may be used to control the voltage applied to the electrodes. The controller may alter the operation of the microfluidic chip in response to fluid sensed at the electrodes.
