Abstract:
Embodiments of the present invention relate to energy storage devices and associated methods of manufacture. In one embodiment, an energy storage device comprises an electrolyte. An anode is at least partially exposed to the electrolyte. A selectively permeable membrane comprising a graphene based material is positioned proximate to the anode. The selectively permeable membrane reduces a quantity of a component that is included in the electrolyte from contacting the anode and thereby reduces degradation of the anode.

Embodiments of the present invention relate to a wearable apparatus. In an embodiment, a wearable apparatus comprises an antenna affixed to a surface of the wearable apparatus. A computing device is in electrical communication with a device. An antenna is in electrical communication with the device. The computing device is formed in a manner to communicate with a mobile device via a first radio frequency. The antenna is formed in a manner to allow the computing device to communicate with a cellular tower via a second radio frequency. The strength of first radio frequency is greater than the signal strength of the second radio frequency. The data transmissions via the first radio frequency are based on an Institute of Electrical and Electronics Engineers 802.11 or 802.15 standard.
Abstract:
Embodiments of the present invention relate to transponder fabrication. In an embodiment, a plurality of antenna elements is applied to a first substrate at a first pitch. A plurality of fully functioning first transponders is positioned on to the first substrate in a manner to each be in electrical communication with an antenna element included in the plurality of antenna elements and thereby forms a plurality of fully functioning second transponders. The plurality of fully functioning first transponders are positioned on a second substrate at a second pitch. The plurality of fully functioning first transponders have a first read range. Second transponders have an increased read range relative to second transponders. The second pitch is greater than the first pitch.
Abstract:
Embodiments of the present invention relate to graphene-based transparent conductors and associated fabrication methods. A first layer having graphene sheets is formed on a substrate. The first layer is transferred to the second layer. The first layer includes graphene sheets. The second layer is transferred to the second layer. The graphene sheets are topically embedded in the second layer in a manner that partially exposes one side of the graphene sheets.
