For decades, the terahertz spectrum has held enormous promise for wireless communication, imaging, and sensing — yet the devices needed to shape these waves have remained rigid, static, and fragile. A research team centered at Capital Normal University in Beijing has now demonstrated that single-walled carbon nanotubes deposited on silicone rubber can form metasurfaces that bend, stretch, and recover without losing their optical function. In doing so, they have transformed a fixed technology into a responsive one — a small material choice with implications that reach toward wearable electronic

China leads THz metasurface development with international collaboration including Russian institutions (RAS, Skolkovo), suggesting continued S&T cooperation despite geopolitical tensions. Western participation (University of Otago, Harbin collaboration) indicates persistent scientific exchange. China's advancement in THz technology strengthens its position in next-generation wireless/imaging capabilities.
Similar to Cold War-era scientific competition in microwave/radar technology, where fundamental physics breakthroughs translated to military advantages. Current international collaboration mirrors pre-2022 patterns of Russian-Chinese-Western scientific partnerships.
