Experimental Soft Matter Physics

Stretchable conductors

As technology is today going more and more towards a wearable form factor, it becomes more and more important to develop electronics that support the flexing and stretching that our clothes are subjected to when we move around. We generally do not take part in the research on flexible electronics, with one exception, and that is the simplest component: the conductor. We have just started doing research on liquid metal alloys, trying to better understand how they can be processed, in particular in a co-flow situation with other liquids, e.g. polymer solutions. If this research is successful, we believe we can produce fibers with a conducting liquid metal core, which could provide the required conductivity and stretchability at the same time.
