Abstract: A wearable apparatus includes an antenna affixed to a surface of the apparatus. A device is in electrical communication with the antenna. A control circuit is in electrical communication with the device and a communications device. The antenna includes a composition that includes a polymer and carbonaceous material made up of individual graphene sheets that are present in the polymer in a three-dimensional percolated network. A mobile device is communicatively coupled to a cellular RF source via a first wireless signal. The control circuit is configured to communicate, using the communications device, with the mobile device via a third RF signal; communicate, using the device, with the RF source via a second RF signal; and cause the mobile device to communicate with the RF source via the third RF signal when the second RF signal is greater than the first RF signal.

Abstract: A wearable apparatus includes an antenna affixed to a surface of the apparatus. A device is in electrical communication with the antenna. A control circuit is in electrical communication with the device and a communications device. The antenna comprises a composition comprising carbonaceous material consisting of individual graphene sheets. The individual graphene sheets are present in the composition in a continuous three-dimensional connected network where individual graphene sheets have nanometer scale separation at contact points between individual graphene sheets. The control circuit is configured to (i) communicate, using the communications device, with a mobile device via a first radio frequency (“RF”) signal; and (ii) communicate, using the device, with a cellular tower via a second RF signal. The signal strength of the first RF is greater than the signal strength of the second RF signal. The first RF signal utilizes an IEEE 802 standard for data transmissions.

Abstract: Embodiments relate to systems and methods to enable communication between computing devices. The system comprises a cellular-based RF source. A mobile computing device(s) is communicatively coupled to the RF source via a first wireless signal received thereby at a first signal strength. An antenna(s) is positioned proximate to the surface of a wearable item and comprises a conductor element(s) fabricated using a polymer(s) and fully exfoliated graphene sheets.
