Invisible paper with Nanotechnology

David Janes, a researcher at the Birck Nanotechnology Center and a professor at the School of Electrical and Computer Engineering, compared electronic paper to the image frames on computer screens that have become popular in the last year.

"Electronic paper has memory space to store multiple documents," he says. "And it is flexible, light and portable, just like a small book."

The paper, which Janes hopes will be available in the next five years, is the result of research conducted at the Birck Nanotechnology Center. A team of teachers and students developed the transparent nanowire transistors and circuits used in electronic paper.

Other researchers had previously made nanowire transistors, but the metal electrodes they used made the structures opaque.

Transparent transistors could allow scientists and engineers to embed displays on car windshields, so drivers can view information and warnings without looking at the dashboard.

The transistors could also be used in displays for surgeons, soldiers and other professions, so that they consult information while they work.
