Finally we can present our T-RING prototype!
In the new T-PAPER video you can see one of the final applications which could be realized with paper-based piezoelectric loudspeakers. A 360° surround-sound installation can be used in exhibition booth as well as for acoustic accompaniment of museum exhibits.
T-PAPER team published their new scientific paper on „Paper-Embedded Roll-to-Roll Mass Printed Piezoelectric Transducers“ in Advanced Materials. Georg C. Schmidt and co-authors could realize an innovative concept for large-area piezoelectric devices on paper made by means of cost efficient roll-to-roll mass printing. Also post printing technologies including inline poling were realized at the Institute for Print and Media Technology.
TU Chemnitz presented in the press release a 360° surround-sound installation made with a 387 cm long paper web consisting of 56 piezoelectric speakers. The paper loudspeaker web including printed wiring weighs only about 150 gramm.
Video clip on T-PAPER project is available on the Youtube channel of TU Chemnitz.
Unfortunately DAGA 2020 was cancelled in according to the latest recommendation of the Ministry of Health in connection with the corona virus.
Nevertheless, we want to present our latest prototype as soon as possible. We will keep you updated!
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!
T-BOOK 2 is a highlight of every exhibition since more than two years and is also showcased at L’atelier 4.20 by Arkema in Paris.
Enjoy the new video clip of Arkema presenting the T-BOOK 2 and other technologies using piezoelectric polymers!
C-Town 360° is a meeting platform for industry and researchers to exchange their ideas and to present technologies, insights and megatrends. The focus of this convention were Smart Systems, Artificial Intelligence and microelectronic technology. We could meet such Start-Ups as LiGenium, Trowis and some others and hear about their solutions for more sustainable manufacturing.
We took part in Deep Dives „Artificial Intelligence“ and „Mechanical Engineering & Digitalization“. Many thanks to CWE Chemnitz and Wirkbau Chemnitz for such inspiring event!
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.
