Klas Tybrandt

Professor, Head of Unit

Principal Investigator at Soft Electronics, Laboratory of Organic Electronics

Presentation

Professor Klas Tybrandt is the PI and unit manager of the Soft Electronics group at 91Ƶ (LiU). The group develops stretchable composite materials, design concepts and devices to adapt electronics for the soft human body.

Klas has published more than 70 peer reviewed articles and is the inventor of seven patents/patent applications. He is the recipient of the ERC Consolidator Grant (2023), Wallenberg Academy Fellow (2022), SSF Future Research Leader (2020), VR starting grant (2019), and SSF Ingvar Carlson Award (2018). Klas is PI within the Wallenberg Wood Science Center (WWSC), the Wallenberg Initiative Material Science for Sustainability (WISE), and the Advanced Functional Materials center at LiU. He also serves in the WISE university representative group for LiU.

Klas Tybrandt received his Master’s degree in Applied Physics and Electrical Engineering from LiU in 2007. Later the same year he started his PhD studies on the topic of organic bioelectronics under Prof. Magnus Berggren (LiU). The work was focused on the development of ionic components and circuits, including the highlights of inventing the first ionic transistor functional at physiological salt concentrations and the first complementary ionic circuits. These inventions and others resulted in a total of three granted patents. In 2012, Klas Tybrandt received his PhD in Organic Electronics and continued to work in the group as a postdoc for a year.

In 2013, Klas received a Postdoc Fellowship from the Swedish Research Council and in early 2014 he joined the Laboratory of Biosensors and Bioelectronics, ETH Zurich, headed by Prof. Janos Vörös. From this point forward he changed his research topic into stretchable electronics, with focus on soft and stretchable materials for bioelectronics.
In 2016, Klas joined the Laboratory of Organic Electronics at LiU as Assistant Professor and established the Soft Electronics group in 2017. Klas earned his docenture in 2018 to become Associate Professor, was promoted to Senior Associate Professor in 2021 and became full Professor in 2024.

Soft gold enables connections between nerves and electronics

Gold does not readily lend itself to being turned into long, thin threads. But researchers at LiU have now managed to create gold nanowires and develop soft, stretchable electrodes that can be connected to the nervous system.
