summary

A CO2 laser turns five bio-based recipes into conductive laser-induced graphene on three sheets and two paints, with the best ink matching polyimide LIG and the conductors outperforming activated charcoal and equaling carbon black. Biodegradable coatings (wax, tape, others) add water and abrasion resistance. Demonstrations include humidity, proximity, heating and bend sensors, reuse of scrap across five recycling rounds, Biolic paper and lignin-ink perform well, the material can lose 95% mass in ~3 days, and the full build-to-sensor workflow takes ~14 hours.
