Scientists invent disposable, paper e-readers.

Wow, e-reading on paper! What will they think up next?? Item!

A breakthrough in a University of Cincinnati engineering lab could clear the way for a low-cost, even disposable, e-reader. Electrical Engineering Professor Andrew Steckl's research into an affordable, yet high-performance, paper-based display technology is being featured this week as the November cover story of ACS Applied Materials and Interfaces.

In the research, Steckl and UC doctoral student Duk Young Kim demonstrated that paper could be used as a flexible host material for an electrowetting device. Electrowetting (EW) involves applying an electric field to colored droplets within a display in order to reveal content such as type, photographs and video. Steckl's discovery that paper could be used as the host material has far-reaching implications considering other popular e-readers on the market such as the Kindle and iPad rely on complex circuitry printed over a rigid glass substrate.

"One of the main goals of e-paper is to replicate the look and feel of actual ink on paper," the researchers stated in the ACS article. "We have, therefore, investigated the use of paper as the perfect substrate for EW devices to accomplish e-paper on paper."
