If the Institute for Print and Media Technology at Chemnitz University of Technology has its way, many loudspeakers of the future will not only be as thin as paper, but will also sound impressive. This is a reality in the laboratories of the Chemnitz researchers, who back in 2015 developed the multiple award-winning T-Book—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 development is continuing all the time,” 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.
