Scientists at Chemnitz University of Technology in Germany have developed paper thin speakers which can be printed on rolls of paper called T-Paper. The paper holds two layers of conductive organic polymer with a piezoelectric layer in between that vibrates to create the sound. T-paper can be shaped into a circle and act as a hanging loudspeaker at events like tradeshows or as part of museum exhibits to broadcast audio information.
