皮膚の湿度を解析するためのピエゾエレクトリックセンサの開発

本研究的目的是设计和制造一种一次性、低成本的石墨烯压电生物传感器，用于监测皮肤创伤的愈合过程，并将其整合到胶原基质贴片中。电极印刷和传感区域沉积正在进行中，因为与巴塞罗那微电子研究所(IMB-CNM-CSIC，西班牙巴塞罗那)合作实现了初步沉积并对其进行了表征。连续对材料样品进行形态和结构表征。在电极沉积后，还进行了电学表征。有关氧化锌沉积的项目任务引起了几个人的兴趣，并发布了涉及氧化锌的CBD工艺的新的合作协议。第一个研究轴线是构建氧化锌/铝锌层状双氢氧化物(LDH)，这是一种类水滑石的离子层状材料，由于其在传感或废水处理方面的吸附和催化性能而引起了越来越多的关注。这项工作的目的是开发一种可重复使用的制造工艺，使大规模纳米结构氧化锌涂层具有高比表面积，用于气体传感应用。这些调查的结果已在即将举行的ICCGE-18会议上提出。

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.
