On March 16 – 19, the T-PAPER team will participate on DAGA – Jahrestagung für Akustik and present their latest ideas and developments.
Dr. Georg Schmidt will give a presentation about T-PAPER technology on March 19. The main aim is to present roll-to-roll method for mass-printing of piezoelectric loudspeakers.
Moreover in our booth we will present prototypes made with our unique printed loudspeaker paper which can be used for different applications like sound books, smart packages, etc.
The annual convention DAGA takes place in Hannover this year. Visit our booth #60 (1st floor) at Hannover Congress Centrum HCC and explore our sound applications with piezoelectric polymer technology!
On September 25, the delegation from the Yamagata University visited the Institute for Print and Media Technology. Thanks to support by Organic Electronics Saxony was able to construct connection with colleagues in the field of flexible electronics. Among participants we could also meet the representatives of some Japanese companies. The T-PAPER team talked about Printed Piezoelectric Polymer Loudspeakers. In conclusion the participants had an opportunity to get a view of the laboratories of pmTUC.
The visit allowed the members of the delegation to gain a more comprehensive understanding of the printed piezoelectric polymer loudspeakers and of printed electronics in general.
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 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.
