Abstract
Embodiments of the instant disclosure relate to dual functioning signaling devices. The device has a signaling unit that includes an active- and semi-passive signaling components. The signaling unit is affixed to and/or positioned within a textile or substrate. The active signaling component includes a transceiver, power source, and input device to allow the user to selectively transmit identifying information. The semi-passive signaling component includes a radio frequency radiator that reflects an EM response signal when exposed to interrogating EM radiation. The operating frequencies of the active- and semi-passive signaling components are configured to not interfere or interference with each other. The active- and semi-passive signaling components both include antenna elements that include a conductive composition that includes fully exfoliated graphene sheets dispersed with a polymer matrix. The textile can be in the form of a pouch, patch, sticker, and/or panel. The textile can be selectably affixed to objects and/or persons.
