Roll to Roll (R2R) Gravure for Manufacturing Penny RFID Tags

After movable type was first invented by Gutenberg at 1452, an method for transferring information dramatically changed the level of human interface from a small number of people to everyone1.  In simple terms, it means people can access and transfer information through printed materials anytime. This printing technology has evolved over the years and the newest innovation is printed electronics. Thus the level of human interface has been changed from a rigid and expensive portable electronic device to lower cost and wearable electronic device—such devices can be worn by humans and affixed to all types of goods. If all goods can have their own electronic ID and instantaneously communicate with their surroundings via wireless means, the idea of ubiquitous printed electronics would be fully realized.
