Creation of printable paper electronics by control of microstructure

本研究旨在实现生物材料的高效利用和高效的电子制造。在非涂布纸上喷墨打印的银纳米油墨线条，由于落入纸的表面毛孔而断裂，没有导电性。为了解决这个问题，一张纸被浸泡在氟化溶液中并疏水处理。这一工艺防止了线条的连续性和导电性。在应用方面，尝试制作了纸基血糖浓度检测传感器。以棉短绒纸浆为传感纸、紫外光固化油墨为微通道的疏水阻挡层、导电聚合物油墨为电极、葡萄糖苷酶固定于电极等基本技术，通过喷墨打印成功地制作了该传感器。

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.
