The Cluster of Excellence livMatS develops completely novel, bioinspired materials systems that adapt autonomously to various environments and harvest clean energy from their surroundings. The intention of these purely technical – yet in a behavioral sense quasi-living – materials systems is to meet the demands of humans with regard to pioneering environmental and energy technologies. The societal relevance of autonomous systems and their sustainability will thus play an important role in their development. The research program of livMatS is characterized by highly interdisciplinary collaboration between researchers from a broad range of fields including engineering, chemistry, physics, biology, psychology, the humanities, and sustainability sciences. | |
Your TasksLiquid crystal elastomers (LCEs) represent an interesting class of materials, as they can undergo significant dimensional changes when properly stimulated, in directions that can be programmed during fabrication, and are thus suitable for the realization of artificial structures with programmable mechanical response. We have developed a technology which allows a pixel-by-pixel definition of the alignment (and thus actuation direction) of these films, with a resolution of about 20 micrometers. This unique structuring capability gives us unparalleled flexibility in defining the two-dimensional actuation behavior of an LCE film. In this new project, we now propose to extend this concept into three dimensions, enabling the realization of bulk actuators which can modulate between multiple pre-determined shapes, with complete flexibility in defining the actuation direction in the bulk of the “crystal”. With high-resolution definition of the mechanical response of the bulk, we expect to be able to realize wide-ranging adaptive mechanical behavior in materials, all of which can be defined in the material design. | |
RequirementsTo address the research challenge defined by this project, we are looking for a highly-motivated scientist or engineer with a strong background in one or more areas including mechanical engineering; chemical engineering; microsystems engineering; or process engineering. Experience in numerical modelling of mechanical systems; chemical synthesis; and/or microfabrication is a plus. The candidate should have completed her or his MSc degree in a relevant field; be fluent in English and capable in German; and have demonstrated ability to work both independently and as part of an interdisciplinary team.
Your documents will not be returned after the application process. For this reason, please submit copies only. The salary will be determined in accordance with TV-L E13. We are particularly pleased to receive applications from women for the position advertised here. Please send your application in English including supporting documents mentioned above citing the reference number 00002644. Application deadline is 08.01.2023.
Application is to be emailed as one MERGED PDF file to positionslivmats.uni-freiburg.de . | |
We offerThe position provides the right candidate with the opportunity to work in an interdisciplinary environment with access to top-equipped laboratories as well as opportunities to network with senior and junior scientists at the University of Freiburg as well as associated research facilities like the Fraunhofer Institut.
