Abstract: A microfluidic driving system includes a first planar electrode, a second planar electrode, a third planar electrode, a fourth planar electrode, a power supply unit and a detection module. The second, third and fourth planar electrodes are disposed parallel to the first planar electrode and face-to-face with the first planar electrode to form an accommodation space for accommodating a fluid. An AC power is provided by the power supply unit and an AC electrical field is applied by alternately connecting the third planar electrode and the fourth planar electrode with the first planar electrode for driving the first fluid and the second fluid to flow; and then AC electrical field is also applied by connecting the second planar electrode to the first planar electrode to mix the first fluid and the second fluid. Finally, a detection is performed upon a mixture of the fluids through the detection module.

Abstract: A micro-fluidic detector applied for detecting analytes in a fluid sample is disclosed. The micro-fluidic detector comprises a mixing area, a flow area and at least one detection module. The mixing area has a conductive top plate and a plurality of first electrodes for mixing a first fluid and a second fluid so as to form the fluid sample. The flow area has two second electrodes, positioned side by side, for driving the fluid sample to flow. The detection module is used for detecting analytes in the fluid sample flowing in the flow area. The mixing area uniformly mixes the first fluid and the second fluid via an electric field generated by applying a voltage potential, with respect to the conductive top plate, to one by one of the first electrodes in the mixing area. The flow area drives the fluid sample via an electric field generated by the second electrodes.
