    摘要： Various methods and systems are provided for fabrication of nanoporous membranes. In one embodiment, among others, a system includes electrode pairs including substantially parallel electrodes, a controllable power supply to control the electrical potential of each of the electrode pairs, and a syringe to eject an electrically charged solution from a needle to form a nanofiber. The orientation of the nanofiber in a nanofiber layer is determined by the electrical potentials of the electrode pairs. In another embodiment, a method includes providing a nanoporous membrane including nanofiber layers between a transferor and a mainmold of a stamp-through-mold (STM) where adjacent nanofiber layers are approximately aligned in different directions. A patterned membrane is sheared from the nanoporous membrane using the transferor and the mainmold of the STM and transferred to a substrate.

    摘要： Various systems and methods are provided for folded patch antennas. In one embodiment, among others, a folded patch antenna includes a patch disposed on an outer side of a flexible substrate and a ground plane disposed on an inner side of the flexible substrate opposite the patch. The flexible substrate is folded to form an enclosed cavity defined by the inner side of the flexible substrate. The ground plane may provide electromagnetic interference (EMI) shielding of the cavity. In another embodiment, among others, a folded patch antenna platform includes a flexible substrate, a folded patch antenna, and a transceiver mounted on the flexible substrate. The folded patch antenna includes a patch communicatively coupled to the transceiver and a ground plane, which are disposed on opposite sides of the flexible substrate.
