This could be a major development in e-readers.
FOX News reported:
No need to wish for access to the library at Hogwarts; you may soon own a book that can refill its pages -- just like magic.
Imaginations are running wild upon news of a breakthrough that could lead to a low-cost and even disposable e-reader. Coining the phrase "E-paper on paper," electrical engineering professor Andrew Steckl and University of Cincinnati doctoral student Duk Young Kim have developed a method that allows colored text and video to be displayed on flexible, organic paper.
Not too unlike pixels on a screen, "electrowetting" involves applying voltage to millions of colored droplets within a display to form the images seen on the paper, Steckl told FoxNews.com.
"We've been working with electrowetting devices for making displays for some time, and I thought it would be great if the kind of devices we build used more natural materials," Steckl said. "You know, renewable materials that we can harvest on a regular basis and then dispose of more naturally as well."
