The development of biocompatible, flexible and stretchable electronic devices is a great challenge. The main goal of the PhD is the design and study of new conductive materials which originality lies in the combination of two crosslinked polysaccharide systems incorporating a conducting polymer. These organic conductive tracks and electrodes will be deposited on stretchable chitosan-PEG films whose mechanical properties can be well controlled. The electrical, mechanical, and structural properties of the materials will be characterized. Their biocompatibility will be assessed by standard assays, and the electrodes will be tested in rodents (biocompatibility and resorbability assays). These biocompatible stretchable electrodes are expected to improve tissue adhesion and prevent scar tissue formation. In general, such conductive stretchable materials would be of high interest to overcome different challenges (stretchability, flexibility, biocompatibility) in the design of implanted or portable biosensors.
