The ability to print flexible RFID tags on curved surfaces is an area of great interest to manufacturers. However, flexible antennas have proven to be a challenge.   As part of the Met@Link project, begun in October 2015, imec, Quad Industries and Agfa recently developed a demonstrator of a plastic 12-bit RFID tag and read-out system featuring screenprinted circuitry.   Quad Industries is a specialist in utilizing screenprinting to produce a variety of touch and switch solutions, smart labels, NFC antennas, batteries and sensors on a variety of substrates, and printed the antenna.   “Quad Industries optimizes the screenprinting methodology to obtain highest conductivity with flexible thin layers, and integrates this into a complete integrated solution,” Wim Willaert of Quad Industries noted.   Guido Desie, R&D manager at Agfa, said that Agfa supplied its Orgacon nanoparticle-based silver inks for this project. “Agfa-Gevaert develops the
