Scientists unveil reusable electronic paper

Researchers in Taiwan envisage that the e-paper will replace paper signs and posters and save huge numbers of trees.

SCIENTISTS IN TAIWAN have unveiled a reusable paper which works without electricity and can be re-written on up to 260 times.

The ‘i2R e-paper’ is coated with a type of liquid crystal and can be erased with the flick of a switch, reports Reuters.

John Chen, who is vice president of the Industrial Technology Research Institute said that the difference between this new e-paper and traditional display devices is the need for electricity. He said that this new technology is closer to how we use normal paper.

Researchers say that i2R is the ideal replacement for paper signs and posters, and that it will have a hugely positive environmental impact.
