    摘要: 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.

    摘要: Methods, devices and systems are provided for wirelessly powering and controlling a lab-on-a-chip device. Direct current (DC) and alternating current (AC) signals can be produced at the lab-on-a-chip device in a wireless manner. In some configurations, integrated RF components and optoelectronic components of the lab-on-a-chip device are used to collaboratively produce the DC and AC signals. In other configurations only optoelectronic components on the lab-on-a-chip system can produce the DC and/or AC signals in response to incident light. By modulating the incident light, AC signals of various frequencies and waveforms can be generated. The DC and AC signals can be used by additional integrated electronic circuits and by a microfluidic chip lactated on the lab-on-a-chip device to control the behavior of the bioparticles in the microfluidic device.

    摘要: The present invention relates to a fluidic intraocular lens inserted into a capsular bag of an eye to replace a crystalline lens. The fluidic intraocular lens may be shaped by elastic membranes bonded to a support ring. The space inside the device may be filled with optically transparent fluid or gel having an index of refraction greater than the index of vitreous humor. The device may be such designed so that the focusing power of the lens can be changed by the deformation of the capsular bag, which may be subsequently controlled by a ciliary muscle.
