Wearable wireless devices: Low cost radio frequency antenna printed with graphene ink

Scientists have moved graphene — the incredibly strong and conductive single-atom-thick sheet of carbon — a significant step along the path from lab bench novelty to commercially viable material for new electronic applications. Researchers have printed a radio frequency antenna using compressed graphene ink. The antenna performed well enough to make it practical for use in radio-frequency identification (RFID) tags and wireless sensors, the researchers said. Even better, the antenna is flexible, environmentally friendly and could be cheaply mass-produced. —> Read More
