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： A prosthetic retina for implantation in an eye having a defective retina is formed from an array of nanowires having a predetermined spatial distribution, density, size and shape implanted in close proximity to the retina. An electrical conductor is formed at a first end of all nanowires in the array of nanowires and placed in contact with a bias source which biases the array. A plurality of electrodes is located on a second end of each of one nanowire or a bundle of nanowires in the array. Each nanowire produces a photocurrent at a corresponding electrode in response to detection of light impinging on the array of nanowires and the photocurrent stimulates one or more neurons adapted for visual perception. In the preferred embodiment, the predetermined spatial distribution mimics a distribution of rods and cones in a normal eye.

摘要： A practical ID nanowire photodetector with high gain that can be controlled by a radial electric field established in the ID nanowire. A ID nanowire photodetector device of the invention includes a nanowire that is individually contacted by electrodes for applying a longitudinal electric field which drives the photocurrent. An intrinsic radial electric field to the nanowire inhibits photo-carrier recombination, thus enhancing the photocurrent response. The invention further provides circuits of ID nanowire photodetctors, with groups of photodetctors addressed by their individual ID nanowires electrode contacts. The invention also provides a method for placement of ID nanostructures, including nanowires, with registration onto a substrate. A substrate is patterned with a material, e.g., photoresist, and trenches are formed in the patterning material at predetermined locations for the placement of ID nanostructures. The ID nanostructures are aligned in a liquid suspension, and then transferred into the trenches from the liquid suspension. Removal of the patterning material places the ID nanostructures in predetermined, registered positions on the substrate.
