The T-PAPER team published their latest study of “Fully Printed Piezoelectric Polymer Loudspeakers with Enhanced Acoustic Performance” in Advanced Engineering Materials. Xunlin Qiu, Georg C. Schmidt, Pramul Muraleedhara Panicker, Ricardo Alonso Quintana Soler, Aravindan Joseph Benjamin and Arved C. Hübler investigated the influence of remanent polarization and the area of the piezoelectrically active layer on the acoustic output of the loudspeakers. Dielectric spectroscopy was used to study the dielectric properties of the printed loudspeakers before and after poling. Due to the remanent polarization the T-PAPER team could realize a much higher sound pressure level than that achieved by previous tests.
Moreover, this work provides a better comprehension of functionality of fully printed piezoelectric polymer loudspeakers.
The Federal Ministry of Education and Research published a report on the last VIP+ Innovation Conference 2019 in Berlin. The T-PAPER team also participated in the Conference 2019. Their printed loudspeaker was presented at the exhibition VIP+UP! .
The aim of the Innovation Conference is a technology transfer from universities to industry. The grant-aided projects have an opportunity to exchange their experiences and to present their latest developments.
The T-PAPER project is funded under VIP+ program by the Ministry of Education and Research since 2017.
The T-PAPER project participated in the 17th International Symposium on Electrets at the University of Limerick.
Dr. Xunlin Qiu talked about “Fully printed polymer layer structures as flexible piezoelectric loudspeaker” and took part in some workshops. He also got a chance to talk about the latest developments of the T-PAPER project with colleagues from Malaysia, Japan, the United Kingdom, China, Denmark and Austria.
Furthermore, the IEEE 17th International Symposium on Electrets was a great opportunity to meet some industrial representatives, such as Bosch Group and Altratech.
T-PAPER had a team meeting to discuss successful last months and to brainstorm about new applications of a T-Paper.
Dr. Georg Schmidt gave update and set new proposals for the next months of the project. All this time we were advancing our technology and moving closer to our final goal! We also welcomed a new team member. Varvara Bachul is responsible for marketing and costing. She will also support the T-PAPER project during commercialization.
Our team consists of researchers from all over the world: Sri-Lanka, Colombia, China, India, Russia and Germany. So we are full of energy and looking forward to the next successful months!
The T-PAPER project goes to the University of Limerick in September.
Dr. Xunlin Qiu will present the latest developments of our technology to the scientific community and manufacturing industry. He will also talk about our T-Box. The IEEE ISE 2019 event includes international guest speakers, workshops and exhibitions. The symposium in Limerick is also an ideal meeting ground for industry to hear from researchers on their latest innovations and practical applications.
On June 19, the T-PAPER project was presented as a successful „Ready to Transfer“ Project within the FutureSAX Innovation Conference in Dresden, Saxony. Many guests visited our booth and some new ideas were born for future commercialisation of the technology. Let’s see what happens within the next months. We will keep you updated…
pmTUC was invited by Chespa to present the current developments of printed electronics and especially the T-Paper project at the XXI. Polygraphical Symposium under the headline „The future starts today“ in Opole, Poland. More than 400 visitors enjoyed a mixed program with technical but also economy and politics related talks.
The presentation of pmTUC was given by Dr. Georg C. Schmidt, project leader, with the title „T-Paper – On the way to roll-to-roll printed loudspeaker paper“. Additionally, a special sounding edition of a coffee-set package incorporating T-Paper was presented for the first time in cooperation with Chespa. This so-called „T-Box“ starts to sound while opening the smart package.
We would like to thank the organizers of the symposium for the opportunity to present our developments to so many guests of Chespa!
On September 9, the „Neue Papiermuseum Düren“ was reopened in a completely new building with modern architecture and a freshly designed exhibition. The exhibition presents many details about and around paper – and of course not only history and state-of-the-art but also very innovative applications where paper plays an important role. We are proud to be part of this „Vision“ section of the museum with our T-Paper.
With the help of an interactive installation, all visitors can listen to a T-Paper loudspeaker poster and can experience this pmTUC innovation.
Feel free to have a look to the website of the museum.

While the T-Paper crew at pmTUC is continously developing new printing process technology for the R2R realisation of the sounding and sensing paper, our first application demonstrator – the T-Book 2 – will be presented for the second time to a broad audience. This time, the book will be visible (and of course audible) at the LOPEC – the largest fair and conference for printed electronics which takes place at Messe Munich from March 13-15. The T-Book will be presented at the booth of the organic electronic association (OE-A) within a competition for novel printed electronic devices and demonstrators (only March 14-15).
Press Release of OE-A
Where is the sound coming from? Where did you hide the speakers? Sounding paper pages? Impossible!
Just some of the questions we had to answer at Frankfurter Buchmesse last week… After many exciting discussions with many different visitors (publishers, book manufacturers, book sellers, technology scouts, etc.) we can proudly say – our new T-Book 2 has surprised. Despite the heavy busy noise of a huge fare hall surrounding us, the sounding book fascinated everybody. Most important for us, we could catch up many interesting ideas for further improvements and applications.
We would like to thank CPI Deutschland for the great chance to be part of its booth and the warm welcome within the team around Oliver Kranert and Robert Höllein.
Furthermore, we would like to thank the Federal Ministry of Education and Research (BMBF) for financial support. You can find a report on the T-Book on the website of BMBF (in German).
