BookmarkMarch 1, 2007 — Scientists at Sony have developed an electronic version of ink, currently used in the E-Reader, that enables thousands of books to be carried around in one portable, energy-efficient case. Ink movement is possible because of millions of transparent, liquid-filled spheres sandwiched between a plastic film. Positively charged white particles and negatively charged black particles float inside the spheres, depending on how the electrical charge is applied to the plastic. Either the black or white particles move to the front of the spheres, forming crisp patterns of black and white.

Newspapers can be cumbersome, books can take up space, and computer screens can be difficult to read. But now a unique technology may revolutionize the way we read.
E Ink Imaging Film is electronic paper that is currently used in the Sony Reader. Thousands of titles, pictures and audio files can be downloaded into one portable, leather-bound case.
"The, the broadest, most dramatic application is electronic publishing -- the ability to have an entire library in a single electronic book," Michael McCreary tells DBIS. He's a physical organic chemist at E Ink Corporation in Cambridge, Mass.
Once an E Ink page is displayed, the Reader uses virtually no power until the page is turned and, unlike a computer screen, can be read in bright light.
"Basically, the way it works is by moving "ink" around," McCreary says.

E Ink scientists are now developing ways to revolutionize the newspaper industry. Consumers would hold a paper-like display but be able to download an infinite number of stories.
"In addition to being immediate, it can be customized to you," McCreary says. "Every newspaper doesn't have to be the same."
The Sony Reader can store and display documents like Adobe PDF files, blogs, RSS feeds, photos and e-books. Scientists are also working on ways to use E Ink in supermarket shelf labels and signs along the highway. Its low-level power consumption is also making E Ink popular in cell phones and watches.
