| Research Abstract |
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.
