E-ink Gadgets :
Everyone's talking today about the new Amazon Kindle 2 e-book reader. The second-generation device features a sleeker profile, a speedier operation, and a host of new features and updated options. Behind all of that, though, is the real brilliance of the mobile reading device: the high-tech "virtual ink" that makes the whole thing possible.

E Ink's "ink" is some complex stuff, too. As its engineers explain it, "electronic ink is a straightforward fusion of chemistry, physics and electronics to create this new material."


Electronic ink is a proprietary material that is processed into a film for integration into electronic displays. Although revolutionary in concept, electronic ink is a straightforward fusion of chemistry, physics and electronics to create this new material. The principal components of electronic ink are millions of tiny microcapsules, about the diameter of a human hair. In one incarnation, each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid. When a negative electric field is applied, the white particles move to the top of the microcapsule where they become visible to the user. This makes the surface appear white at that spot. At the same time, an opposite electric field pulls the black particles to the bottom of the microcapsules where they are hidden. By reversing this process, the black particles appear at the top of the capsule, which now makes the surface appear dark at that spot.
