The MIT 礛edia Lab

The MicroMedia Laboratory, which is a part of the MIT Media Laboratory, is focused on creating new electronic media and contains many different projects.
The picture you see above demonstrates our goal of creating paper with microencapsulated cells that can freely rotate. Applying electrical charge to these capsules change their orientation and thus the same cells can display different images.
Projects

Electronic Paper Books and Electronic Books

Dr. Joseph M. Jacobson, Barrett Comiskey, Patrick Anderson, and Leila Hasan

Books with printed pages are unique in that they embody the simultaneous, high-resolution display of hundreds of pages of information. The representation of information on a large number of physical pages, which may be physically turned and written on, constitutes a highly preferred means of information interaction. An obvious disadvantage of the printed page, however, is its immutability once typeset. We are currently developing electronically addressable paper-page displays that use real paper substrates. This effort includes the development of novel electronically addressable contrast media, microencapsulation chemistry, and desktop printing technologies to print functional circuits, logic, and display elements on paper or paper-like substrates, including interconnecting vias and multi-layer logic.

Here are some snapshots of pictures taken under the microscope.

Here are some movies showing how electronic paper works.

Reversible Paper

Reversible Paper

Dr. Joseph M. Jacobson, Perry Tsao, and Holly Gates

In a given organization, thousands of pages of material are printed only to be read once and discarded. We are developing a desktop printer and reusable paper substrate capable of producing a high-quality, high-contrast image, which may subsequently be erased and rewritten multiple times without any expendable materials, such as toner or chemicals. Current related investigations include the development of color substrates and the development of electronically addressable, extremely high-resolution color wall-coverings, public message boards, whiteboards, and art canvases.

Digital Portrait Digital Portrait

Holly Gates, Leila Hasan, Jon Heiner, Shishir Mehrotra, Jesse Geraci, Diana Buttz, and Matthew Blum

The digital portrait project is focused on creating large posters with the reversible printer, thus allowing users to print a new poster on the same piece of paper without ever using any ink, paper, or any additional resources. One placnned objective of this project is to allow one to print the front page of a newspaper and have it be updated automatically every day without requiring viewers to do anything.
