University of Cincinnati researchers have developed a low-cost, paper-based, disposable e-reader. The researchers say the paper could be used as a flexible substrate for an electrowetting (EW) device. EW can display content such as text, photographs, and video by applying an electric field to colored droplets within a display. The technology was developed by Cincinnati professor Andrew Steckl and doctoral student Duk Young Kim. "One of the main goals of e-paper is to replicate the look and feel of actual ink on paper," Steckl says.

The researchers found that the new EW technology performed similarly to glass-based devices. "With the right paper, the right process, and the right device fabrication technique, you can get results that are as good as you would get on glass, and our results are good enough for a video-style e-reader," Steckl says.
