Creation of printable paper electronics by control of microstructure

该研究旨在有效利用生物材料和高效电子制造。在非涂布纸上喷墨印刷的银纳米墨水线条没有获得导电性，因为线条落入纸的表面孔中而断裂。为了解决这个问题，将一张纸浸入氟化溶液中并进行疏水化处理。该过程确保了线路的连续性和导电性。在应用中，尝试制作了测量血糖浓度的纸质体检传感器。几种基本技术，例如棉绒浆的传感器纸、紫外线固化墨水的微通道疏水屏障、导电聚合物墨水的电极以及电极上的葡萄糖苷酶固定，全部通过喷墨印刷成功地制造了传感器装置。

This research aims at efficient utilization of biomaterials and efficient electronics manufacturing. No electroconductivity was obtained with silver nano-ink lines printed by ink jet on non-coated paper because of breakage of the line due to falling into surface pores of paper. To solve this problem, a sheet of paper was immersed in a fluorinated solution and hydrophobized. This process prevented ensured the line continuity and electroconductivity. In application, paper-based medical check-up sensor to measure the concentration of blood sugar was tried to be fabricated. Several elemental technologies such as sensor paper from a cotton linter pulp, hydrophobic barrier of a micro-channel from a Ultra-Violet curable ink, electrodes from an electroconductive polymer ink, and glucosidase fixation on the electrode fabricated the sensor device successfully all by ink jet printing.
