TL;DR: In this paper, trathin sheets of polymer LEDs that emit light even when being crumpled or stretched have been realized, and they could prove useful for integration with textiles.
Journal ArticleDOI
Arrays of ultracompliant electrochemical dry gel cells for stretchable electronics.
Martin Kaltenbrunner,Gerald Kettlgruber,Christian M. Siket,Reinhard Schwödiauer,Siegfried Bauer +4 more
TL;DR: Dry gel cells that withstand stretch ratios up to 100% before failure are demonstrated and can deliver power to stretchable electronics, based on the integration of highly elastic carbon black silicon oil paste electrodes into a stretchable acrylic elastomer.
Journal ArticleDOI
Intrinsically stretchable and rechargeable batteries for self-powered stretchable electronics
Gerald Kettlgruber,Martin Kaltenbrunner,Christian M. Siket,Richard Moser,Ingrid Graz,Reinhard Schwödiauer,Siegfried Bauer +6 more
TL;DR: In this paper, a soft matter based rechargeable electrochemical power storage element for stretchable electronic circuits is presented, which is based on a rechargeable alkaline manganese battery concept.
Journal ArticleDOI
From Playroom to Lab: Tough Stretchable Electronics Analyzed with a Tabletop Tensile Tester Made from Toy‐Bricks
Richard Moser,Gerald Kettlgruber,Christian M. Siket,Michael Drack,Ingrid Graz,Umut D. Cakmak,Zoltan Major,Martin Kaltenbrunner,Siegfried Bauer +8 more
TL;DR: A tester is presented that is not only a versatile demonstration device in mechanics, electronics, and physics education and an eye‐catcher on exhibitions, but also a powerful tool for stretchable electronics research.
Journal ArticleDOI
Direct writing of anodic oxides for plastic electronics
Christian M. Siket,Christian M. Siket,Nadine Tillner,Andrei Ionut Mardare,Amir Reuveny,Carina Daniela Grill,Florian Hartmann,Gerald Kettlgruber,Richard Moser,Jan Philipp Kollender,Takao Someya,Achim Walter Hassel,Martin Kaltenbrunner,Siegfried Bauer +13 more
TL;DR: In this article, a scanning droplet cell microscope is used to anodize the pre-deposited thin metal films to form dielectric layers with good control in both lateral dimension and vertical thickness.
