Abstract
Techniques, devices and systems are described for incorporating a printed circuit with a microfluidic device and wirelessly powering the microfluidic device. In one aspect, a microfluidic device includes a substrate with a fluidic channel to provide a path for a fluid with particles. The fluidic channel includes fluid inlet and outlet. A pair of electrodes near the inlet and the outlet guides the particles toward a center of the fluidic channel using negative-dielectrophoresis (DEP) effect in response to an alternating current (AC) frequency voltage received at the pairs of electrodes. Additional pairs of electrodes are disposed along a border of the fluidic channel between the pairs of electrodes near the inlet and the outlet of the fluidic channel to isolate a subpopulation of the particles using positive and negative DEP effects in response to AC voltages of different frequencies received at different ones of the additional pairs of electrodes.
