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。通过喷墨印刷在非涂布纸上的银纳米油墨线没有获得导电性，因为由于落入纸的表面孔中而导致线断裂。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。这一过程保证了线路的连续性和导电性。在应用方面，尝试制作了一种纸基血糖浓度检测传感器。几种基本技术，如来自棉短绒纸浆的传感器纸，来自紫外线可固化墨水的微通道的疏水屏障，来自可聚合物墨水的电极，以及葡萄糖苷酶固定在电极上，均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.
