The purpose of the proposed research is to design and manufacture a disposable and cost effective piezoelectric graphene-based biosensor for the monitoring of healing process of skin wounds and its integration into a collagen matrix patch.The deposition of piezoelectric layer (ZnO) has been intensively investigated, and this task is completed. Electrodes printing and sensing area deposition are under progress as a preliminary deposition was realized and characterized in collaboration with the Institute of Microelectronic of Barcelona (IMB-CNM-CSIC, Barcelona, Spain). Aa morphological and structural characterization are continuously performed on material samples. Electrical characterization was also performed after the deposition of electrodes.The project task regarding ZnO deposition has raised several interests, and new collaborations have been issued involving CBD process of ZnO. The first research axis consists in building ZnO/Al-Zn Layered Double Hydroxides (LDH) which are hydrotalcite-like ionic lamellar materials that have raised a growing attention due to their adsorbent and catalytic properties for sensing or liquid waste treatment. The aim of this work is to develop a reproducible manufacturing process that would enable a large scale nanostructured ZnO coating with a high surface area for gas sensing applications. The results of these investigations was presented at the upcoming ICCGE-18 conference.
