A Hacker News thread discusses a new method of creating Laser-Induced Graphene (LIG) from commercial inks and dyes, dubbed "Paint & Scribe." The method allows LIG tracks to be integrated onto various surfaces, including printed and flexible electronics. Furthermore, the process enables the creation of freestanding and transferable LIG by dissolving acrylic paint and floating LIG in water.
One commenter expresses excitement about the potential, while another is skeptical, citing the common gap between lab results and commercialization. The discussion also questions the specific advantage of using inks and dyes over alternative sources like recycled plastic or fruit peels. The original paper highlights the method's ability to create LIG on any wettable surface and facilitate LIG transfer. A commenter questions why this method is specific to ink and dyes when fruit peels may be an alternative solution.
