A folded planar antenna device for radio frequency identification (RFID) reading is provided. The folded planar antenna device includes an RFID chip, a conductor member comprising a binocular-shaped slot; and a substrate. The conductor member is mounted on the substrate and the substrate is connected to the RFID chip through the binocular-shaped slot. The folded planar antenna device can be mounted on different objects, such as metal, meat, or liquid container, without being completely de-tuned.

The present invention is directed to photovoltaic and photogalvanic devices and methods of generating electrical energy and power or detecting light therefrom, based on a novel nano-enhanced bulk photovoltaic effect using non-centrosymmetric crystals, including ferroelectric and piezoelectric materials, where the non-centrosymmetry is the equilibrium state or it is static or dynamically induced. In certain embodiments, the device comprises a layer of non-centrosymmetric crystalline materials, and a plurality of electrodes disposed in an array upon or penetrating into at least one surface of the crystalline material, the electrodes being optimally spaced to capture the ballistic carriers generated upon irradiation of the crystalline material.
