Okay, so maybe they’re allowed to brag — the concept of “erasable” e-paper does sound pretty cool. The Taiwanese researchers have shown off the capabilities of their paper, which only costs about $2 per A4 sized sheet. It can be rewritten around 260 times before it needs to be replaced.
The “paper” actually doesn’t involve any actual paper, in case you hadn’t guessed that already. The plastic coating is covered with liquid crystal, which creates a really interesting visual effect. By manipulating the crystal, different colors of this “paper” can also be displayed.
Right now, this erasable paper is called “I2RE paper”. The researchers behind its creation are hoping that it will become available to consumers in around a year, but that’s a tentative guess.
