Printed Electronics: The First Step towards a R2R Printing Foundry via a Complementary Design Rule in Physical Dimension for Fabricating Flexible 4‐Bit Code Generator (Adv. Electron. Mater. 12/2020)

A basic R2R electronics printing foundry concept comprising nanomaterial based electronic inks, R2R printing speed, overlay printing registration accuracy, and device design is described by Gyoujin Cho and co‐workers in article number 2000770. They demonstrate their system by printing 44 single walled carbon nanotube (SWCNT)‐based p‐type and n‐type TFTs to integrate a ring oscillator, six NAND gates, and a OR gate for 4‐bit code generation through a R2R gravure printer.
