Though having ‘loudspeakers printed on standard paper’ is something hard to comprehend for many, research is already taking place with ‘Printer Loudspeakers’, a revolutionary technology called made possible using flexography. This work is being undertaken at the Chemnitz University of Technology  in Germany. 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 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 piezo-active layer and is printed in the laboratories of pmTUC. This German University is already seeing an enormous potential for its 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?
