    Abstract: A lens structure includes a transparent cell containing a liquid crystal material. The cell is thicker in a center region thereof than at peripheral regions. The structure further includes transparent electrically conductive electrodes coupled with opposing top and bottom surfaces of the cell and configured to establish an electric field through the cell that is strongest at the peripheral regions where the cell is thinner relative to the center region so that a value of the index of refraction of the liquid crystal material changes across the cell from the center region towards the peripheral regions to change an effective focal length of the lens structure. In some embodiments the top surface of the cell has a first curvature C1 and the bottom surface of the cell has a second curvature C2 that differs from the first curvature.

    Abstract: A nanopore FET sensor device and method of making. The nanopore FET sensor device includes a FET device stack of material layers including a source, channel and drain layers, and a nanoscale hole through the FET device stack to permit flow of strands of molecular material, e.g., DNA, therethrough. The perimeter of the nanoscale hole forms a FET device gate surface. The source and drain layers are provided with respective contacts for connection with measuring instruments that measure a flow of current therebetween. The molecular strands having charged portions pass from one side of a wafer substrate to the other side through the (nanopore) gate and modulate the current flow sensed at the source or drain terminals. The sensor collects real-time measurements of the current flow modulations for use in identifying the type of molecule. Multiple measurements by the same nanopore FET sensor are collected and compared for enhanced detection.
