    摘要： Embodiments of the present invention relate to a symmetrical printed radio frequency identification antenna and method of forming a radio frequency identification antenna. In one embodiment, the radio frequency identification antenna comprises a loop element having a plurality of sides. A first conductive element is in electrical communication with the loop element. A second conductive element is in electrical communication with the loop element. The first conductive element includes an integrated circuit pad. The first and second conductive elements extend in opposite directions substantially from a middle portion of a side included in the plurality of sides. The loop, first conductive element, and second conductive element are electrically conductive. The second conductive element includes a quadrilateral portion. The second conductive element has a width that is at least about the length of the side included in the plurality of sides.

    摘要： Embodiments of the present invention relate to graphene-based capacitive sensors. In one embodiment, a touch sensor comprises a non-porous insulating substrate having a first side and a second side. A first conductive material is at least partially in communication with the first side. A second conductive material is at least partially in communication with the first side. A third conductive material is at least partially in communication with the second side. The first conductive material and the second conductive material are in communication. The first conductive material forms a linearization pattern. The first conductive material includes a metal. The second conductive material and/or third conductive material comprise graphene sheets.

    摘要： Embodiments of the present invention relate to a symmetrical RFID antenna and method of formation. In one embodiment, the radio frequency identification antenna comprises a loop element having sides. A first and second conductive elements are in electrical communication with and extend opposite from a middle portion of a side. A third and fourth conductive elements are in electrical communication with and oppositely extend from a second side. A fifth conductive element extends from a vertex of the second conductive element to a vertex of the forth conductive element. The second and/or forth conductive elements comprise a quadrilateral portion. The second and/or forth conductive elements comprise a width that is at least about the length of a side included in the plurality of sides.
