Emerging technologies such as smart packaging, wearables and environmental monitoring are shifting the requirements on electronic components, notably regarding the immense number of devices and their short service life, which counts in days instead of years. As a result, standard materials are often not adapted due to economic, environmental or manufacturing considerations. Instead, more sustainable strategies need to be considered combining the use of renewable resources with efficient processing to create materials designed for recyclability or environmentally safe disposal. In this talk, I will share some of our work using cellulose as a renewable and integral component for multifunctional printed materials and devices with applications in energy, sensing and robotics.

Gustav Nyström received a Ph.D. in engineering physics from Uppsala University in 2012. Following postdoctoral work at KTH Royal Institute of Technology in Stockholm and ETH Zurich, he is since 2018 Head of the Cellulose & Wood Materials laboratory at Empa and a Lecturer at ETH Zurich. His research aims to develop active, renewable, and highly functional biomaterials using cellulose and biopolymers as material resources.
