Epishine’s ”light cell” can change how we power small electronics – a thin and flexible organic solar cell that can be integrated in sensors, consumer electronics and other low power devices to reduce or eliminate the need of batteries.

If the Institute of Print and Media Technology at Chemnitz University of Technology in Germany has its way, many speakers of the future will not only be as thin as paper, but will also have an impressive sound. This is a reality already in the laboratories of the Chemnitz researchers, who developed the multiple award-winning "T-Book" back in 2015 – a large-format illustrated book equipped with printed electronics. If you turn a page, it begins to sound through a speaker invisibly located inside the sheet of paper. "The T-Book was and is a milestone in the development of printed electronics, but the development continues," says Prof Dr Arved C. Hübler, under whose leadership this technology trend, which is becoming increasingly important worldwide, has been driven forward for more than 20 years.
