Researchers attempt to print thin-film transistors with metal oxides onto heat-sensitive materials

Within the Functional Oxides Printed on Polymers and Paper (FOXIP) project, researchers form Empa, EPFL and the Paul Scherrer Institute attempted to print thin-film transistors with metal oxides onto heat-sensitive materials such as paper or PET. The goal was ultimately not achieved, but those involved consider the project a success—because of a new printing ink and a transistor with "memory effect."
