Leitungselement und Antenne in Tintendrucktechnik

摘要

A printing process is provided in which a conductive ink is printed over a printed pattern formed by a coating having an additive that lowers surface tension. Printed electrical elements and antennae (including RFID antennae) are formed using this process. The coating with the surface tension lowering additive is printed on a substrate in a predetermined pattern. A conductive ink is then applied over the coating and, because of the difference in surface tension between the coating and the substrate, the ink flows away from the coating. The conductive ink dries between the printed coating pattern and forms the conductive element.
