Kyoto Institute of Technology and Chuo University have developed a cooling-free infrared sensor using semiconductor carbon nanotubes (CNTs) with 11x greater sensitivity than conventional materials. Building on Japan's legacy in CNT research since their 1991 discovery at NEC, this breakthrough could transform autonomous driving, security screening, and medical imaging. Here's what it means and how Japan is reacting.
As AI's explosive growth makes chip power consumption a critical global issue, Japan's next-generation chip technologies are drawing worldwide attention. Tohoku University's MRAM memory reduces power consumption to 1/100th of conventional chips, while Saga University's diamond semiconductors — called the "ultimate semiconductor material" — advance toward space and 6G applications. We report on Japan's technological edge and the intensifying competition with the US and China.
No batteries. Just 280 grams of rubber. A Japanese bone-setter turned entrepreneur created "futto," a walking support device using rubber tubes as artificial muscles. Built with hardware store materials by a 3-person family company, it's now scientifically validated and expanding overseas. Here's how this $220 innovation tackles aging societies worldwide.
Beef tendon, a common Japanese hot pot ingredient, is being transformed into knee ligament implant material. A Waseda University startup has developed decellularization technology that could eliminate the need to harvest patients' own tissue for ACL reconstruction. Clinical trials are underway with commercialization targeted for 2028.
Osaka-based Satosen's liquid metal stretchable circuit board has been officially adopted by ATR-Promotions for biosignal measurement electrodes. With self-healing wiring that withstands over 250,000 stretch cycles, this technology opens doors for wearable devices, flexible displays, and soft robotics.
Tohoku University and the University of Tokyo have developed DIVE, a multi-agent AI workflow that automatically reads and structures experimental data from scientific paper figures. By extracting over 30,000 data points from 4,000+ papers, the system proposed new hydrogen storage materials in just 2 minutes. Here's how this AI reading team is unlocking data trapped inside research charts.
A joint research team from the University of Yamanashi, Waseda University, and Shinshu University has developed a completely fluorine-free electrolyte membrane for polymer electrolyte fuel cells. Achieving over 100,000 durability cycles—1.3 times that of conventional fluorine-based membranes—this PFAS-free breakthrough could accelerate the global hydrogen economy while addressing environmental regulations.
Mizuno and Kaneka's co-developed biodegradable artificial turf "Re Green Grass 9" has been installed at Vantelin Dome Nagoya — a world first for professional sports facilities. Using Kaneka's "Green Planet" biopolymer that decomposes even in seawater, this innovation tackles the growing microplastics crisis in sports infrastructure.
Fujikura dominates the global market for high-temperature superconducting wire essential to fusion reactors. Combined with Japan's domestic AI-powered autonomous driving, artificial photosynthesis breakthroughs, and the government's Physical AI strategy, these technologies are putting Japan back on the global innovation map.
A joint team from Chiba University, NHK Science & Technology Research Labs, and Kyoto University has developed an organic EL device capable of both light emission and solar power generation.
