Biography
Martin Kaltenbrunner is a full professor at the Johannes Kepler University Linz, heading the Soft Matter Physics Division and the LIT Soft Materials Lab. Prof. Kaltenbrunner received his master’s and PhD degrees in physics from the Johannes Kepler University in 2008 and 2012 working with Siegfried Bauer. He then joined the Someya-Sekitani Lab for Organic Electronics at The University of Tokyo as postdoctoral researcher, leading the “Imperceptible Electronics Team”. Returning to JKU in 2014 as Assistant Professor, he obtained Habilitation (Venia Docendi) in Experimental Physics in “Soft Electronics” in 2016. In 2019, he was appointed Full Professor at the Johannes Kepler University. His research group specializes in soft electronics and soft transducers, in particular on sustainable and biodegradable elastic materials and processes for skin-inspired electronics and embodied robotics. They are pioneers in soft and stretchable batteries and solar cells as well as ultrathin and lightweight electronic foils. The group develops materials strategies, design rules and technologies including resilient yet degradable soft and elastic substrates, passive and active components and power sources that enable green wearable (bio)electronics and soft robots. Kaltenbrunner is on the editorial board of Advanced Materials and Advanced Intelligent Systems, recipient of a Starting Grant of the European Research Council, has published >66 papers and given over 70 invited/keynote/plenary lectures. He has been an active member of MRS since 2008.

[Abstract]
Modern societies rely on a wide range of electronic and robotic systems, with emerging stretchable and soft form factors enabling an ever more intimate integration of the digital and biological spheres. These advances however often take their toll on our ecosystem, with high demands on energy, contributions to greenhouse gas emissions and severe environmental pollution. Mitigating these adverse effects is amongst the grand challenges of our society and at the forefront of materials research. The currently emerging forms of soft, biologically inspired electronics and robotics have the unique potential of becoming not only like their natural antitypes in performance and capabilities, but also in terms of their ecological footprint.
This talk introduces materials and methods or soft systems that facilitate a broad range of applications, from sustainably powered, transient electronic skins to metabolizable soft robots. Based on highly stretchable biogels and degradable elastomers, our forms of soft electronics and robots are designed for prolonged operation in ambient conditions without fatigue, but fully degrade after use through biological triggers. Electronic skins provide sensory feedback such as pressure maps, strain, temperature and humidity sensing. Recent advances in 3D printing of biodegradable hydrogels enables omnidirectional soft robots with multifaceted optical sensing abilities. Tackling the challenge of autonomous operation, soft, stretchable and biodegradable batteries are introduced that power wearable sweat sensors. Pushing the boundaries further, design concepts that exploit mechanical instabilities for fast actuation in soft robotics systems to environmentally friendly cooling systems based on the giant elastocaloric crystallization effect are demonstrated.
