Robotic Materials Talk 22-08-2024 Technologies of Thin Films for High-power Laser Systems High-power laser systems significantly influence solutions for major scientific issues and high-tech industries. Thin films are one of the core components of advanced high-power laser systems. With the development of output power and application scenarios, high-power laser systems have to satisfy increasingly stringent requirements on the damage threshold, optical loss, and capabilities of optical field control for thin-film components of laser systems. In terms of improving the laser damage threshold, we revealed a physical mechanism of "localized strong point", which will induce laser d... Christoph Keplinger

Robotic Materials Talk 18-03-2024 Bioadhesive Technologies with Mechanical Principles Bioadhesive technologies are important in a wide range of applications, spanning from wound management to wearable technologies. Forming and controlling tough adhesion on biological tissues has been a long-lasting challenge, necessitating transdisciplinary approaches. In my talk, I will share our recent progress in the design, mechanics, and applications of tough bioadhesives. I will first discuss the limitations of clinically used surgical glues and blood clots in terms of adhesion properties. I will then present the mechanical principles for making tough bioadhesives that exhibit superior... Christoph Keplinger Adrian Koh

Robotic Materials Talk 18-07-2023 Nature-inspired designs for innovating soft robotic grippers and prosthetics In this talk, I will discuss the cutting-edge research conducted at our Soft Robotics Research Center and Biorobotics Lab, with an emphasis on the development of grippers and prosthetics inspired by the adaptive behaviors and embodied intelligence observed in nature. Traditional robots are designed for structured environments and navigate unstructured environments using sensors and intricate computation. To adapt to and flourish in unstructured environments, nature employs simple embodied intelligence, which does not necessarily require sensing or complex computation. Christoph Keplinger Metin Sitti

Robotic Materials Talk 12-05-2023 Instability-driven Pattern Formations for Dynamically Tunable Functionalities in Soft Magneto-Active Materials Nature actively uses sophisticated designs of microstructures to achieve astonishing material properties and functionalities. Thus, microstructures give rise to the incredible toughness of mother-of-pearl. Another example is an octopus, an amazingly effective soft machine created by nature. The creature can squeeze its whole body through an extremely narrow space while preserving a large variety of functionalities. The nature-created soft machine comprises highly deformable composites that are characterized by different dynamically tunable microstructures and phase properties, depending on ...

Robotic Materials Talk 25-07-2022 ELECTRETS (Dielectrics with quasi-permanent Charges or Dipoles) A long History and a bright Future Electrets have a long history starting more 2600 years ago and a bright future in the areas of soft transducers, plastic electronics, radiation dosimeters, air filters, etc. From the beginning, the similarities, the differences, and the combinations of dielectric and magnetic materials, of positive and negative “electricities”, of internal hetero-charges and external homo-charges, etc. have been puzzling natural philosophers and scientists. At the same time, rather slow, but continuous progress in the understanding and the application of electrets has been made. Recently, the essential role... Christoph Keplinger
