On the morning of December 4th, in the first comprehensive clinical trial ward of brain computer interface in China, which was jointly established by Tianjin University Brain Computer Haihe Laboratory and Tianjin Huanhu Hospital, a monitoring device equipped with brain computer interface technology displayed real-time changes in intracranial pressure of patients. In the past, obtaining such data often required a craniotomy surgery. Here, brain computer interfaces are no longer the "black technology" in science fiction works, but a key tool integrated into daily diagnosis and treatment. From the laboratory to the clinical ward, from basic research to industrial promotion, the Tianjin University Brain Computer Haihe Laboratory team protects people's health with brain computer interface technology in a warm and firm way. Professor Liu Xiuyun, Deputy Director of the Medical Department and Deputy Director of the Brain Computer Haihe Laboratory at the university, said, "The introduction of brain computer interfaces and intelligent medical technology in the experimental ward has truly brought medical engineering integration technology into the medical service scene." In the experimental ward, a patient who lost the ability to hold a pen due to stroke is experiencing an "idea driven" attempt. He wears a brain electrode cap on his head, carries a lightweight main control module "backpack", and uses the "sixth finger" worn on his wrist to grab the water bottle on the table. After several attempts, when the bottle finally left the table, the patient's eyes became moist. This "sixth finger" is the "miracle worker - Lingxi finger" developed by the Haihe Laboratory of Brain Computer Science at Tianjin University. It relies on non-invasive brain computer interface technology to collect brainwaves, allowing patients to use the "sixth finger" motor imagination paradigm to control external prostheses with their thoughts, while stimulating the damaged nervous system for rehabilitation training. Postdoctoral researcher Wang Zhuang, who was recording data on the side, participated in the entire process from concept validation to clinical trials. He said that the team's original intention for creating brain computer interfaces was very simple, 'If mind control can be achieved, then it should be used in the places that can best help patients'' regain their lives'. '. The brain is described by the scientific community as the most complex 'universe', and brain computer interface technology enables this' biological computer 'to establish precise information channels with the external world. As one of the six future industries proposed for forward-looking layout in the 15th Five Year Plan, it is regarded as a new engine for future economic growth, alongside quantum technology, biomanufacturing, hydrogen and fusion energy, embodied intelligence, and sixth generation mobile communication. I am fortunate to have caught up with the era of accelerated national technological innovation. ”Liu Xiuyun recalled the year when he returned to China to teach in 2021, coinciding with the acceleration period of brain computer interfaces worldwide. As a young scholar at the intersection of neurology, critical care medicine, and biomedical engineering in China, she almost lives her life in seconds. Her figure is often seen running all the way between the laboratory, ward, and conference room. The Proposal of the Central Committee of the Communist Party of China on Formulating the 15th Five Year Plan for National Economic and Social Development proposes to "forward-looking layout of future industries, explore diverse technological routes, typical application scenarios, feasible business models, and market supervision rules". Liu Xiuyun said that as early as the 14th Five Year Plan period, the team had set its sights on the field of brain diseases, and through brain computer interface technology, achieved real-time "observation" of the brain that integrates "diagnosis monitoring treatment prediction", truly embedding technology into the treatment chain. The Fourth Plenary Session of the 20th Central Committee of the Communist Party of China clearly proposed to "accelerate high-level technological self-reliance and self-improvement, lead the development of new quality productive forces", and emphasized the need to "strengthen original innovation and key core technology research and development". This is also the action guide of the Haihe Brain Computer Laboratory team at Tianjin University for many years. For many years, the team has been continuously conducting systematic research and development in the field of non-invasive brain computer interfaces, covering the entire chain innovation from underlying chips, core algorithms to system integration. At present, the team has the world's largest patent pool in the field of brain computer interaction, with an international patent market share of over 10%. Brain computer interface technology is a 'Tianjin University business card' that focuses on national strategic needs, deeply cultivates basic research and technological breakthroughs, and promotes deep interdisciplinary research. ”Tianjin University President Chai Liyuan stated that the Fourth Plenary Session of the 20th Central Committee of the Communist Party of China has made a systematic deployment to promote the development of education, science and technology talents. This calibration follows this deployment, conducting leading and original research in cutting-edge fields such as brain computer interfaces, promoting the transformation of high-value achievements, and striving to bring more disciplinary directions into the world-class arena.
