Bionics and Transduction Science

In the BTS unit we do research in the interface between biology, material science, transducers and microsystem technology.

graphic showing the three research areas

Starting from a perspective of application/user needs, we do applied and fundamental research in the areas of microphysiological devices (e.g. lab/organ on a chip), electroactive surfaces for cell biology, soft microactuators and soft microrobotics, and textile actuators and textile exoskeletons.

Research projects

Mechanostimulation chips

Microphysiological Systems

We are developing mechanostimulation chips that can mechanically stimulate single cells. Mechanotransduction pathways in the urinary tract are of special interest to us.

Textile exoskeletons and exoskeletons

By combining advanced textile manufacturing and conducting polymer actuators with have developed novel textile actuators.

Electroactive surfaces and scaffolds

In this project we look into various dynamic surfaces to control cell adhesion, signalling, proliferation and stem cell differentiation.

Soft microactuators and microrobotics

In this project we research on various soft microrobotics, used for development of medical devices such as steerable guide wires and catheters for minimal invasive surgery.

More about our research

Edwin Jager, IFM, along with his co-applicant Nils-Krister Persson at Swedish School of Textiles

Continued funding for textile muscles

Edwin Jager (IFM) along with his co-applicant Nils-Krister Persson (Swedish School of Textiles) recently received the exciting news of continued funding for their project "Textile muscles for augmenting garments" from the Erling-Perssons Foundation.

Bone growth inspired “microrobots” that create their own bone

Inspired by the growth of bones, researchers have developed a combination of materials that can morph into various shapes. The material is initially soft, but later hardens through a process that uses the same materials found in the skeleton.

Two projects receive grants from Horizon 2020

LiU has been awarded two EU-funded Marie Skłodowska-Curie Individual Fellowships for international postdocs. The projects will look at soft microrobots and how cancer spreads to the bones.
