Brain computer interface, biomimetic dual arm robots, the world's first wearable underwater thruster, and underwater search and rescue robots... On November 15th, the 25th China International High tech Achievements Fair (hereinafter referred to as the "High tech Fair") opened, and a batch of cutting-edge technologies and products will be showcased. The theme of this year's High tech Fair is "stimulating innovation vitality and improving development quality", and the "one exhibition, two pavilions" linkage exhibition mode will continue to be adopted. It will be held simultaneously at the Shenzhen Convention and Exhibition Center (Futian Exhibition Area) and Shenzhen International Convention and Exhibition Center (Bao'an Exhibition Area), with a scale of 500000 square meters. It is the largest high tech fair in history. The High tech Fair, founded in 1999, is known as the "First Exhibition of Science and Technology in China" and is regarded as an important "vane" for insight into new trends in the development of high-tech industries and meeting new market demands. Every year, it attracts numerous advanced technologies and innovative products to appear. On the afternoon of the 14th, when the reporter visited the museum, he saw that the booth layout had entered the final stage, and many high-tech equipment had also entered the site for final debugging. There were a variety of exhibits in the fields of artificial intelligence, 5G applications, low altitude technology, clean energy and so on. In the booth of Chinese Academy of Sciences Shenzhen Advanced Technology Research Institute in Hall 8 of Futian Exhibition Area, a huge colorful brain model is eye-catching. The on-site staff told reporters that the device can vividly display the neural circuits corresponding to different brain diseases such as epilepsy to the audience. As the "old face" of the 18th China High tech Fair, the institute has presented over 200 high-tech exhibits at the fair this year, covering high-end medical devices, synthetic biology, brain science, advanced materials, big data, biopharmaceuticals, carbon neutrality, and more. After the first "Specialized, Refined, and New" exhibition was established at last year's High tech Fair, a "Specialized, Refined, and New" exhibition group was set up in the Futian exhibition area, covering a total area of over 5000 square meters. A group of "Specialized, Refined, and New" enterprises made collaborative appearances, showcasing cutting-edge technologies and products in AI technology, intelligent chips, mobile communication technology applications, digital entertainment technology, advanced robots, and the Internet of Things. In the Bao'an exhibition area, over 2000 high-quality enterprises have made their debut with new products. At the "Aerospace Low Altitude Technology Exhibition" that debuted at the China High tech Fair, the Xiaopeng Huitian Land Air Integrated Flying Vehicle will be showcased to the public for the first time in its latest form, and the Zhihang drone will debut with the newly developed domestically produced world's first electric vertical takeoff and landing manned flying saucer; Galaxy Aerospace will also showcase the charm of China's first flat stacked satellite, Lingxi 03, using a large flexible solar wing on site. Huawei, Baidu, Alibaba Cloud, DJI, as well as French companies such as Veolia, American companies such as Selemer, Danish companies such as Grundfos, and German companies such as Weile, have appeared at the water-saving industry exhibition, showcasing advanced water-saving technology products, excellent water-saving practice cases, and solutions. The two major exhibition halls of Futian and Bao'an each have their own focuses, and there is a free public transportation system between the two halls. Transportation lines connect city landmarks such as CBD, Hetao, High tech Zone, Qianhai, Airport, and Exhibition City. The High tech Fair not only creates a "press conference" for new products, but also builds a "reception hall" for enterprise exchanges, strengthens mutual assistance and cooperation between government, industry, academia, and research, cultivates an open innovation ecosystem, and enables technology to benefit the world. This year, there will be over 100 countries worldwide
