“와, 정말 기발한 발상!” 딱풀 하나로 미래 기술을 만들다｜YTN 교양있게

What if the "grass thread" game you played at least once as a child became cutting-edge technology of the future? A thin thread made solely from fingers and grass demonstrates remarkable strength, and when combined with the nanomaterial graphene, it has transformed into a cutting-edge sensor capable of conducting electricity. Starting from a simple idea, the research team is developing an ultra-fine "grass thread sensor." Possessing strength comparable to a spiderweb, this thread can withstand the weight of dozens of coins and has the unique characteristic of reacting only to specific liquids. In particular, they succeeded in fabricating an electrically conductive thread by utilizing reduced graphene oxide (rGO), a conductive nanomaterial. The resulting sensor demonstrates outstanding performance, capable of detecting nitrogen dioxide (NO₂), a harmful substance found in automobile exhaust gases, within seconds. An amazing sight where a brilliant idea born from childhood play leads to future environmental sensors and next-generation nanotechnology! Check out the video to see the immense scientific possibilities created by a single drop of grass. 👉 Subscribe to the Cultured Channel    / @교양있게2025   #Nanotechnology #Nanoscience #Graphene #AdvancedTechnology #FutureTechnology #ExhaustGas #ScienceExperiment #ScienceandTechnology #Science #Technology #NewMaterials #AdvancedMaterials #Nanomaterials #KScience #Invention #TechnologicalInnovation #FutureIndustry #Environment #Sensor #Nano #YTN #GoldenCompass
