The Nuremberg International Invention Exhibition held from the 26th to the 28th in Germany attracted exhibitors from about 30 countries and regions, showcasing more than 500 innovative inventions in various fields. The Chinese exhibition group showcased 96 innovative achievements, becoming a key "treasure trove" for exhibitors and investors from various countries to explore. At the Tsinghua University exhibition area, a row of small vessels with various shapes of objects attracted the attention of many exhibitors. Zhang Songyan, a doctoral student from the School of Aerospace Science of Tsinghua University, gently picked up a piece of soft butterfly shaped hydrogel composite material with tweezers and put it into the instrument. This soft, like a flying "butterfly" was fixed into a specific shape after a moment. Zhang Songyan explained that the "butterfly" was made of a fiber reinforced, 3D printable hydrogel composite. "We have added some aramid nanofibers to improve its mechanical properties, so that its modulus, strength and toughness are close to human tissues," said Zhang Songyan. Professor Zhang Wei from the institute told reporters that they have developed an original sequence to enhance the proliferation and killing activity of CAR-T cells, in order to achieve efficient and specific killing of glioma cells. In ongoing clinical trials, this therapy has demonstrated good therapeutic efficacy and safety. In recent years, the participation of Chinese universities, research institutes, and innovative enterprises in international scientific and technological exchange activities has been increasing. At this exhibition, the Chinese delegation has 24 universities, 17 enterprises, and 9 research institutes, with invention projects covering fields such as healthcare, construction, water conservancy, computers, instrumentation, electronic communication, and household appliances. The team from Beihang University has brought an intelligent "muscle like" control torque gyroscope product, which has been applied in aviation, navigation and other scenarios, effectively improving the survival ability of unmanned systems in complex environments. Beijing Graphene Technology Research Institute brings a new generation of AIHF? Ivor Graphene Thermal Management Technology uses far-infrared radiation generated by graphene materials to resonate with human cells at the same frequency, producing a thermal effect that relieves muscle fatigue, reduces muscle tension, and achieves pain relief. He Zhenfu, Vice Chairman of the China Invention Association, believes that the invention projects brought by the Chinese exhibition not only showcase China's strength and potential in the field of technological innovation, but also provide rich cooperation opportunities and commercial value for global investors. He Zhenfu said, "The Chinese invention community opens its arms and embraces the world. We look forward to China's invention and innovation achievements showcasing their charm on the international stage and contributing more Chinese wisdom to the progress and development of human society
