Researchers at Taiwan's Industrial Technology Research Institute are giving the world a peek at i2R, a new type of easily erasable e-paper. The technology uses a thermal printer and cholestric liquid crystals, letting users write and erase its contents up to 260 times. It can print different colored inks and could potentially be used for things like ID badges and signage. The sheets currently cost around $2 a piece to produce and should be available to us consumer types in about two years.
