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具有成本效益的一次性压电石墨烯生物传感器，用于监测皮肤伤口的愈合过程并将其整合到胶原基质贴片中。压电层（ZnO）的沉积已经得到了深入的研究，这一任务已经完成。随着与巴塞罗那微电子研究所（IMB-CNM-CSIC, Barcelona, Spain）合作实现并表征了初步沉积，电极印刷和传感区域沉积正在进行中。对材料样品进行了连续的形态和结构表征。电极沉积后也进行了电学表征。关于ZnO沉积的项目任务引起了人们的兴趣，并且已经发布了涉及ZnO CBD工艺的新合作。第一个研究方向是构建ZnO/Al-Zn层状双氢氧化物（LDH），这是一种类似水滑石的离子层状材料，由于其在传感或液体废物处理方面的吸附剂和催化性能而受到越来越多的关注。这项工作的目的是开发一种可重复的制造工艺，使具有高表面积的大规模纳米结构ZnO涂层用于气敏应用。这些调查的结果将在即将召开的icge -18会议上公布。

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.
