On April 23, the latest research results of the brain-computer interface team of Zhejiang University were released in the Second Affiliated Hospital of Zhejiang University School of Medicine (hereinafter referred to as the Second Hospital of Zhejiang University). It is understood that its latest research has realized the brain-computer interface for writing Chinese characters for the first time, and successfully realized the invasive brain-computer interface to control the robotic arm to write Chinese characters, and the "mind writing" that can only be seen in science fiction movies has been reflected into reality.
At present, the team's latest research focuses on brain-controlled Chinese character writing, relying on this technology, patients only need to imagine the normal writing process, which can be reflected by the neuronal activity in the motor area, and through the analysis of nerve signals in the motor area, they can obtain their imagined writing trajectory and control the robotic arm to write.
At present, the brain-computer interface team of Zhejiang University has broken through the special coding mechanism of Chinese character writing, and developed a new technology for decoding the trajectory of Chinese character writing on this basis, which has achieved a classification accuracy rate of 91.3% for 100 commonly used Chinese characters in the offline state, and an online accuracy rate of 96.2% with the assistance of language models.
-- The development of brain-computer interface products
Brain-computer interface related research and development has been carried out in bionics, medical diagnosis and intervention, consumer electronics and other fields, from the perspective of product development, at present, the mainland's representative brain-computer interface enterprises strong brain technology, brain technology, soft technology and so on have launched a series of consumer-level brain-computer interface products, the application scope covers children's education, entertainment, medical, health and other fields.
-- Layout of the technical direction of brain-computer interface enterprises
Invasive or semi-invasive brain-computer interfaces require hardware implants such as chips in the brain, which will destroy the natural physical protection system of the brain and cause problems such as surgical trauma, bleeding, and infection of the human brain. If the relevant software and hardware facilities are illegally used, it may also cause brain disorder, and in severe cases, it may lead to brain damage and endanger life safety. In addition, invasive brain-computer interfaces have a higher technical and financial threshold than non-invasive ones, so non-invasive brain-computer interfaces are still the mainstream technology route in the market.
According to Enniu data, among the companies that have received financing in the brain-computer interface industry in mainland China, only a few companies such as Brain Tiger Technology, Ningju Technology and Boruikang Technology have laid out the invasive brain-computer interface industry, and other companies are focusing on the research of non-invasive brain-computer interface products.
——The development trend of the brain-computer interface industry
In recent years, although a large number of start-ups have appeared in the mainland brain-computer interface industry, and the number and amount of patent applications, financing events and amounts have increased significantly, from the application level, brain-computer interface products are still far from large-scale industrialization. In order to promote the progress of brain-computer interface technology and realize the industrialization of brain-computer interface, the state proposes to strengthen basic research such as brain science and promote the popularization of brain science on the one hand, and on the other hand, encourage brain-computer interface enterprises to accelerate the application of products in typical fields such as medical treatment, rehabilitation, virtual reality, and education.
According to McKinsey's research report, the global annual market size of brain-computer interfaces from 2030 to 2040 may be between 70 billion US dollars and 200 billion US dollars (about 510 billion to 1.4 trillion yuan).
According to the analysis of Zheshang Securities Research Report, with the continuous maturity of brain-computer interface technology, its application scenarios are rapidly opening. At present, brain-computer interface and neurorehabilitation are hot technologies in the field of neural engineering, which have attracted the attention of more and more scientific research scholars and clinicians, and are expected to rapidly promote the implementation and popularization of products in the future.
