Electronic waste is a growing problem in a digitalized world. By developing electronics based on biomass derived and biodegradable materials, the use of finite resources and generation of electronics waste can be minimized. This is particularly important for wearable electronics and Internet-of-Things devices, which come in large numbers of relatively short lifetime.

Sustainable wearable energy devices

Sustainable wearable energy devices are crucial as the capacity of batteries scales with the amount of material and conventional battery chemistries utilizes rare and toxic materials. To address this, we develop biomass-derived materials and concepts around abundant raw materials, which together improve the sustainability of energy devices substantially. Softness and stretchability of wearable batteries is achieved through innovative design concepts, materials and device structuring.

Printed wearables

Printed wearables can combine conformal form factors with sustainability through printed electronics processing. Printed electronics can reduce the amount of waste and the use of hazardous solvents in comparison to conventional electronics by patterning in an additive manner. In collaboration with Research Institute of Sweden (RISE) we develop materials and devices for printed wearables.

Efficient cooling technology

Efficient cooling technology has the potential to reduce the enormous energy consumption related to cooling in our modern society. Here we explore novel concepts for personalized cooling and solid state cooling based on the unique mechanical properties of soft electronics.
