Printed Paper Speakers Created by pmTUC Provide Good Sound Quality

The thin loudspeakers, which are printed in the laboratories of pmTUC, contain several layers of a conductive organic polymer and a piezoactive layer. According to project assistant Maxi Bellmann the loudspeakers are astonishingly robust and can be produced in a very cheap way as mass printing methods are used. The bottom side of the paper loudspeaker provides unused space on which coloured messages can be printed.
