The T-Paper looks like this. It is said that 90% of the whole is made of conventional paper, so even if it is called a speaker, it looks like ordinary paper.
In the following movie, project manager Georg C. Schmidt explains how T-Paper was developed.
T-Paper was developed at Chemnitz University of Technology as part of a 20-plus-year-old development project for printed electronics. In 2015, Chemnitz University of Technology developed the book ' T-Book ' made of paper speakers, but the paper speakers used in the T-Book are 'ordinary paper layers' and 'conductive organic'. It has a two-layer structure of 'polymer layer', and it was necessary to make each one by hand.
With T-Paper,
You can also connect several T-Papers to create a surround environment. In the image below, seven T-Papers are connected to form a 360-degree audio system. The total weight including the circuit is only 150g.
'T-Paper enables low-cost information display in museums, trade fairs, the advertising industry, etc. It can also be installed in corridors to provide a uniform acoustic experience,' Schmidt said. I have high hopes that T-Paper will be used for various purposes.
