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.

Your clothes will soon be extra muscles

Textile muscles is a young research field. In the long run, the technology can be built into clothes that can give an extra boost during heavy lifting, give hugs at a distance and help the visually impaired navigate the urban environment.

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.
