Paper Electronics to be Addressed at Printed Electronics USA Conference

Intrinsiq and Novacentrix can now print copper patterns on paper with a considerable potential saving in cost over silver for antennas, electrodes, sensors, switches, keyboards, conductors and metamaterials. The University of Helsinki has developed its own versions.

Previously, printed copper would oxidise and become insulating and useless. Printed copper has a huge future but it will not replace all silver because it is not allowed in contact with food in marketed products, it can become electrochemically active and it poisons OLED displays, for example.
