On July 1, Musk’s Neuralink announced the completion of the world’s first brain-computer interface (BCI) implantation surgery via a trans-dural approach. This procedure entirely eliminates the step of incising the dura mater, instead allowing electrode threads to directly penetrate the dura and implant into the brain parenchyma. This innovation aims to reduce surgical trauma, shorten recovery time, and lay the groundwork for broader clinical applications in the future. This latest development has once again placed brain-computer interface technology in the global spotlight of both the tech industry and capital markets.
In China, the brain-computer interface (BCI) sector is also entering a period of explosive capital growth, with financing in the primary market accelerating comprehensively. Early this year, the announcement of BrainCo’s RMB 2 billion funding round ignited an investment frenzy in the sector. A few days ago, its official teaser for the global debut of a brain-controlled robot training platform also drew widespread attention within the industry. According to data from IT Juzi, as of June 30, there had been 64 financing and investment transactions in the BCI sector, totaling approximately RMB 7.253 billion—far exceeding the total transaction volume for the entire year of 2025.
Behind the fervor lies the epoch-making significance represented by brain-computer interface technology itself.
Today, brain-computer interfaces are establishing pathways between the human brain and silicon-based peripherals. In the future, activities that rely on human perception of the environment, decision-making, and execution of operations may all find entirely new modes of implementation through this technology. It is precisely this versatility, which transcends physical constraints, that prevents it from being confined to any single niche sector; instead, it is exploring practical applications across fields such as healthcare, consumer electronics, human-computer interaction, and gaming entertainment.
In medical rehabilitation, brain-computer interface (BCI) systems are helping patients regain motor function; in the field of education, they can capture and regulate attention states in real time; and in consumer electronics and human-computer interaction, BCIs are also delivering more immersive experiences.
Based on the degree of invasiveness to the brain, brain-computer interfaces (BCIs) can be categorized into three major types: non-invasive, semi-invasive, and invasive. Neuralink, founded by Elon Musk, and Merge Labs, invested in and co-founded by Sam Altman, have bet on invasive and non-invasive approaches, respectively, becoming key bellwethers for investment and financing in this sector.
In China, the brain-computer interface (BCI) industry is characterized by the parallel development of three distinct pathways, each targeting different application scenarios and corresponding to varying commercialization paces and investment logics. The invasive approach, featuring high risk and high reward, is better suited for capital with a long-term investment horizon. The non-invasive approach has already achieved commercial implementation, offering a clear path to scalable revenue and attracting diverse industrial capital with its low-risk, stable-return profile. The semi-invasive approach falls between these two extremes.
The Technological Divide Between Invasive and Non-Invasive Approaches
Invasive brain-computer interfaces, by virtue of their direct contact with the cerebral cortex, offer high signal precision and signal-to-noise ratio, making them a core technological pathway for tackling severe neurological disorders. Key research efforts are focused on minimizing implantation trauma and ensuring long-term stability in vivo. Nevertheless, this approach entails stricter medical device regulatory requirements and prolonged clinical validation periods.
The core challenge of non-invasive approaches lies in the “extreme signal-to-noise ratio (SNR) outside the body”: the skull attenuates more than 80% of neural electrical signals, resulting in the acquisition of weak microvolt-level signals that are heavily contaminated with various types of interference. Accurately decoding human motor intentions, emotional states, and even thought content from such noisy signals presents engineering challenges in signal processing and algorithmic decoding that are no less formidable than the precision challenges associated with surgical implantation—akin to clearly hearing every word of a whisper on the other side of a wall.
This is also why dry electrodes and deep learning decoding algorithms have become the core focus of non-invasive approaches. Companies represented by BrainCo have independently developed solid-state gel electrodes, overcoming the scalability bottlenecks of traditional wet electrodes that require conductive paste and cumbersome setup. Paired with low-noise circuit design, these electrodes achieve a signal-to-noise ratio of 10.78 dB in real-world EEG testing. Building on this foundation, their high-performance neural signal decoding algorithms can fuse multimodal physiological signals, converting intention into motion commands within 200 milliseconds, with motion intention recognition accuracy leading the industry.
Globally, the upper limit of non-invasive precision is continually being redefined. In June 2026, Meta, in collaboration with the Basque Center on Cognition, Brain and Language in Spain, released the Brain2Qwerty v2 model, which increased the decoding accuracy of non-invasive brain-computer interfaces from 8% to 61%, approaching the performance levels of certain invasive solutions. In the field of haptic feedback, BrainCo has achieved a bidirectional closed loop from environmental perception to neural feedback. By identifying object characteristics through flexible tactile sensors and converting contact information into micro-stimuli perceptible to the human body, the system enables users to perceive subtle environmental changes via neural and electromyographic pathways, thereby enhancing the immersion and operational precision of human-computer interaction.
Simultaneous Implementation in Healthcare and Consumer Sectors: The Commercialization Prospects of Non-Invasive Brain-Computer Interfaces
Global Support for the Brain-Computer Interface Industry: A Highly Consistent Underlying Logic—Encouraging Technological Innovation, with Greater Emphasis on Safety, Accessibility, and Public Benefit
The U.S. NIH’s “BRAIN Initiative” and related DARPA research have consistently supported parallel development of multiple approaches, including non-invasive ones. In its Human Brain Project and AI regulatory framework, the EU has imposed strict requirements on the safety and ethics of brain-computer interfaces, prioritizing technically feasible solutions with controllable risks and broad applicability.
Meanwhile, domestic policies are also paving a clear path for the industrial implementation of brain-computer interfaces.
In July 2025, the Ministry of Industry and Information Technology (MIIT) and six other departments jointly issued the “Implementation Opinions on Promoting the Innovative Development of the Brain-Computer Interface Industry,” which outlined a two-phase roadmap. The document proposes accelerating the application of brain-computer interface products in fields such as industrial manufacturing, healthcare, and consumer lifestyle by 2027. The core orientation is to drive progress through scenario-based implementation, ensuring that technology truly serves real-world needs.
Notably, non-invasive technologies have been deployed across multiple niche scenarios, leveraging their safety, non-invasiveness, and short implementation cycles. In terms of product certifications, offerings such as BrainCo’s intelligent bionic prosthetics and ADHD rehabilitation training systems have sequentially obtained authoritative approvals from the FDA and NMPA, addressing diverse clinical needs including limb function reconstruction and neurodevelopmental disorders. From a reimbursement perspective, the National Healthcare Security Administration has established independent billing codes for non-invasive brain-computer interfaces, with regions such as Zhejiang and Beijing subsequently incorporating them into medical insurance coverage, thereby continuously strengthening commercial sustainability.
Beyond medical rehabilitation, brain-computer interfaces (BCIs) also hold market potential in the consumer sector. As early as around 2010, Muse launched a neurofeedback headband focused on sleep and meditation training, while Emotiv’s EPOC opened up another market segment in game development and human-computer interaction research.
Recently, brain-computer interfaces (BCIs) have continued to achieve breakthroughs in human-computer interaction capabilities. According to an announcement by BrainCo, a highly dexterous bionic hand with 21 degrees of freedom has been iteratively deployed. At the upcoming World Artificial Intelligence Conference in Shanghai, its first brain-controlled robotic system, neural data acquisition solutions, and other cutting-edge achievements will also be unveiled. These innovations provide foundational support for the development of embodied intelligence from both ends: signal decoding and data supply.
These cumulative advances point to a more accessible future, as brain-computer interfaces (BCIs) move out of the laboratory and permeate diverse scenarios: aiding attention enhancement in education, creating immersive experiences in entertainment, providing precise health interventions for consumers, and establishing a neural interaction foundation for embodied intelligence.
Truly epoch-making technologies ultimately derive their value from “ubiquity.” This holds true for electricity, the internet, and likewise for brain-computer interfaces (BCIs). When a technology serves only a select few, it remains merely a frontier exploration within the laboratory; only when it enters everyday life at an affordable cost and with convenience does it truly usher in an industrial era. On the long journey of BCIs transitioning from technological innovation to widespread accessibility, the non-invasive approach is taking the lead in entering the critical phase of industrialization.
