Unfurtunately the monastery Irsee has been closed by the Bavarian government due to the corona virus.

Therefore we have decided to offer the conference as a web conference only.

In those unpredictable times, protecting our participants’ health has the highest priority for us!

The scientific exchange must not come to a complete standstill and we believe that with this web solution we have found a way to keep the scientific community going.

In order to participate in the livestream of the conference as easy as possible and to give your presentation, we recommend the use of the web browsers Google Chrome or Microsoft Edge.

Here you can find detailed instructions for using the livestream.

As a participant of the Bioinspired 2020 you have received an e-mail containing the login data for the web conference.

The login data for the sessions are provided daily.

In order to allow all conference participants access to the posters, we ask you to upload your poster by login on the conference homepage and clicking on the button "My Submission" in the upper right corner of the conference homepage. Then select the submission to which you want to upload the poster and upload the poster at the bottom of the page.

Furthermore we would like to ask all poster authors to prepare 4 PowerPoint slides to present your poster to the audience.
Please also include your contact details on the digital poster to allow participants to reach you with questions.

Please note that your poster will be pictured publically.

As poster author you can upload your poster similar to the way you submitted your abstract.
Click on "My Submissions" in the upper right corner at the homepage.

Poster documents can be found by opening the respective abstract in the online programme.
If a poster document has already been uploaded for the abstract, it can then be opened and downloaded.

Please note that your poster will be pictured publically.

You can ask your questions via chat already during the presentations!
Please use for this the Q&A (F&A) button!

For further scientific exchange we implemented a discussion forum on the homepage of the DGM.
Please visit and use your DGM or Bioinspired user credentials to login.

Poster with short presentation

Nacre-inspired thin film stretchable electrode

Monday (16.03.2020)
17:32 - 17:35

Numerous nacre-inspired composite materials has been introduced with exceptional mechanical properties in structural materials. However, few study on electrical composite materials is reported. Here, we introduced 'Nacre-inspired stretchable thin film electrodes' by exploiting the use of polydimethylsiloxane (PDMS) as substrate, and inevitable low-molecular weight (LMW) PDMS on the surface. The diffused LMW PDMS in the metal grains and layers will act as a viscoelastic glue similar to the ‘protein organic layer’ in the ‘brick-and-mortar’ structure of natural Nacre, allowing the brittle metal platelets to frictionally slide when the structure is stretched. Furthermore, the ultrathin thickness together with the sparse structure of the molecular layer can provide an electrical path between the interlayers of the metal films via an electron tunnelling effect. Thereby,the materials shall maintain a high conductivity under mechanical deformation, enabling the production of stretchable electrodes.
