New Conductive Inks Make RFID Tags Better, Smaller

"The application team at Creative Materials Inc. a worldwide leader in inks, coatings and adhesives, has developed a highly conductive ink for printing RFID antennae. Passive RFID tags have antennae that can absorb radio waves from an interrogator device. The tags use the received radio energy to power an electrical circuit that generates a unique identifier, and sends a reply. The interrogator receives the reply, allowing it to know the unique identification of the RFID tag. One of the challenges in designing RFID tags is the need to print antennae and circuits that are small, durable, and not too expensive." Source: eMediaWire
