In the TUCscicast Dr. Georg Schmidt responds the questions about the latest developments of T-PAPER technology, advantages of the printed electronics today as well as the ideas for the future applications on the basis of printed paper lodspeakers. You will find the TUCscicast in every podcast app!
New T-PAPER video by TU Chemnitz
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.
Our scientific paper in Advanced Materials
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.
T-PAPER at DAGA 2020
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!
Japanese delegation visited pmTUC
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.
New scientific paper published
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.
VIP+ Report of the Federal Ministry of Education and Research
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.
T-PAPER presented at the IEEE ISE 2019 in Ireland
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 put their heads together about remaining months of the project
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!
T-PAPER at ISE 2019 – 17th International Symposium on Electrets in Ireland
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.
