    Though having 'loudspeakers printed on standard paper' is something hard to comprehend for many, Institute for Print and Media Technology of Chemnitz University of Technology (pmTUC) research is here with 'Printer Loudspeakers', a revolutionary technology called made possible using flexography. So now, the tech guys present you with a technology that converts ink to sound. The printed paper is connected to an audio amplifier to give us a considerably loud sound. The researchers claim that the frequency response and the sound quality are very good.

    This paper is made up of several layers of a conductive organic polymer and a piezoactive layer and is printed in the laboratories of pmTUC. This German Tech is already seeing an enormous potential for it's applications in the advertising segment. We may soon see water bottles with papers wrapped around them that play advertisement jingles of the company.


    Apart from printed loudspeakers, the Chemnitz researchers have exhibited a solar tree that features 50 printed solar leaves. These leaves collect solar energy and cable built in the hollow tree trunk supplies electricity for a battery. What's interesting to see here is how the researchers have envisioned the merger of electronic media and print media in near future. "If you stand below the tree and look up to the shade-giving leaves of the solar tree, you can see that the bottom side of the leaves is printed with advertisements”, explains Prof. Dr. Arved Hübler, head of pmTUC. How innovative is that? Check the following video and share your reactions through comments.
