"PROCESS FOR THE OPERATION OF A MICROFLUID SYSTEM, MICROFLUID SYSTEM, MICROFLUID POWER SUPPLY SOURCE AND USE OF A SUBSTRATE, POWER POWER AND MICROFLUID SYSTEM". In a microfluidic system (partially illustrated by element 178 in the figure and elements on it) using electrokinetic forces, the present invention uses electrical current or electrical parameters, different from voltage, to control the movement of fluids through the system channels. Time multiplexed power supplies (200 and 202) also provide additional control over fluid movement by varying the voltage at an electrode connected to a fluid reservoir in the microfluidic system, by varying the duty cycle during which the voltage is applied to the electrode, or through a combination of both. A time multiplexing power supply can also be connected to more than one electrode to save costs.
