(May 20, 2015) Scientists
at The University of Manchester have revealed a graphene antenna capable of
delivering cheaper, more powerful and more sustainable RFID tags and wireless
sensors.
Made from compressed graphene ink, the antenna is flexible,
environmentally friendly and could be cheaply mass-produced, paving the way for
wearable wireless devices and sensors.
Radio-frequency identification (RFID) tags wirelessly
transfer data in a vast range of everyday objects, from car assembly to
tracking household pets. Graphene, the world’s strongest, thinnest and most
conductive material, could dramatically increase the conductivity of RFID tags.
