Large Integrated Circuits Produced in a Printing Press

Researchers have printed complete integrated circuits with more than 1,000 organic electrochemical transistors. Printing electronic circuits with a line width of approximately 100 micrometers places high demands on print technology. To solve the problem, the team developed screen-printing frames with meshes that can print extremely fine lines and printing ink with the right properties. The material used is the polymer PEDOT:PSS.
