Research: Fully roll-to-roll gravure printable wireless sensor-signage tags for smart packaging

Integration of sensing capabilities with an interactive signage through wireless communication is enabling the development of smart packaging wherein wireless (13.56 MHz) power transmission is used to interlock the smart packaging with a wireless (13.56 MHz) reader or a smart phone. Assembly of the necessary componentry for smart packaging on plastic or paper foils is limited by the manufacturing costs involved with Si based technologies. Researchers at the Printed Electronics Research Institute in Korea obviated the issue of manufacturing cost for smart packaging by materials that allow R2R (roll-to-roll) gravure in combination with R2R coating processes to be employed.
