What other magical uses do ordinary markers you have seen in addition to writing? Tokyo startup, Japan AgIC has developed a silver marker ink, which has a conductive function, draws lines on special paper, and turns the paper into a circuit board when you turn on office supplies, just like magic. AgIC President Shimizu Nobuya said that students can use ink to draw different lines, conduct current experiments, combine learning with entertainment, and arouse interest in learning. On the other hand, advertising companies can also combine special ink and paper to create luminous promotional leaflets for office supplies to attract consumers. In the future, wallpaper can even be turned into a circuit board with sensors to monitor elderly people living alone. The special feature of this new technology is that it can print circuits on paper several meters wide, the paper can be folded, and the ink can be applied with correction fluid. The AgIC ink dries quickly and can be printed with an inkjet printer.
