China is strengthening its position in brain-computer interface technology by helping establish international standards for systems that connect the human brain with computers and external devices. The new international reference architecture provides a common framework for describing BCI systems, their functions and how their components work together. The development could help reduce technical fragmentation as researchers and companies move the technology toward wider use.
The effort also reflects China’s ambition to shape the emerging brain-tech industry through standardisation, research and commercial development. Beijing is preparing a broader set of national standards covering medical devices, industrial applications and consumer technology. As competition intensifies among Chinese companies and international players such as Neuralink, common standards could become increasingly important for interoperability, safety and commercial adoption.

What Is China’s New Brain-Computer Interface Standard?
The new international standard establishes a reference architecture for brain-computer interfaces. In simple terms, it provides a shared way to describe the major parts of a BCI system and how they interact.
The framework addresses four basic questions: what a BCI is, how it is used, what functions it provides and how it is implemented. This helps reconcile differences in system components, functional divisions and implementation methods across technologies and application scenarios.
The standard was developed under the leadership of a Chinese project manager, with experts from countries including Italy, South Korea, the United Kingdom, India, the United States, Japan, Sweden, Finland and Australia.
The involvement of experts from multiple countries is significant because BCI development is not limited to one national market. A common technical reference can make it easier for researchers, manufacturers and standards organisations to communicate about system design and future requirements.
China’s national reference-architecture standard, GB/T 47023-2026, was issued on January 28, 2026, and took effect on August 1, 2026. The international standardisation effort builds on this broader work to establish shared technical foundations for the industry.
How Brain-Computer Interfaces Work
A brain-computer interface creates a communication pathway between the nervous system and an external device. Depending on the technology, the system records brain activity, processes the signals and uses algorithms to interpret patterns associated with a person’s intentions.
A BCI might translate a pattern of brain activity into a command to move a cursor, select a letter or operate an assistive device. Some systems use sensors placed outside the skull, while others use implanted or surgically positioned electrodes to capture signals more directly.
The basic process can be divided into several stages:
- Signal acquisition: Sensors or electrodes record brain activity.
- Signal processing: Software filters noise and prepares the signals for analysis.
- Decoding: Algorithms identify patterns associated with intended actions.
- Application: The decoded output controls a computer, prosthetic or other device.
- Feedback: The user receives information about the result, allowing interaction to continue.
A common reference architecture helps developers describe these stages consistently, even when individual products use different hardware or algorithms.
Why Standardisation Matters for the BCI Industry
BCI systems combine neuroscience, electronics, software, artificial intelligence and medical engineering. Without shared technical definitions and testing approaches, different products can use incompatible data formats, inconsistent evaluation methods or different assumptions about system design.
Standardisation can address several of these challenges.
Interoperability between systems
Common architectural principles can help developers understand how components fit together. This does not automatically make every BCI device compatible with every other device, but it provides a foundation for more consistent design and future interoperability standards.
More consistent testing and evaluation
Medical and assistive BCI products need reliable ways to evaluate their performance. Common terminology and technical frameworks can help researchers and manufacturers compare systems and communicate results more clearly.
Different applications will still require different tests. A system designed to help a person regain hand movement has different safety and performance requirements from a non-invasive device used for entertainment.
A clearer path from research to commercialisation
Standards can reduce uncertainty for manufacturers, suppliers and potential customers. They can also help regulators and testing organisations develop consistent approaches as new types of devices enter the market.
However, compliance with a technical standard is not a substitute for clinical evidence or regulatory approval. In particular, medical devices must demonstrate that they are safe and effective for their intended uses.
China’s Plan to Build a Larger BCI Standards System
China’s international standardisation work is part of a broader national strategy.
Under draft guidelines released by the Ministry of Industry and Information Technology, China aims to formulate or revise more than 40 BCI standards by 2028. It also intends to encourage at least 100 companies to adopt the standards and lead or participate in the development of more than 10 international standards.
By 2030, the country aims to have developed more than 80 standards, creating a more comprehensive framework for the domestic industry.
| Target | China’s stated ambition |
|---|---|
| BCI standards by 2028 | Formulate or revise more than 40 |
| Company adoption | Encourage at least 100 companies |
| International standardisation | Lead or participate in more than 10 standards |
| BCI standards by 2030 | Develop more than 80 |
These are policy targets, not evidence that all the standards have already been completed or adopted.
The programme is intended to support an industry that China has identified as a future-growth sector. It covers more than the design of brain implants, extending to data, system performance, evaluation and other technical areas.
AI Is Becoming an Important Part of Brain-Computer Interfaces
Artificial intelligence is increasingly important to BCI systems because brain signals are complex and can vary between individuals and over time. Algorithms help identify meaningful patterns and translate them into commands that a computer or assistive device can understand.
China has also moved to standardise the datasets used by AI-enabled BCI medical devices.
A Chinese medical-device standard covering datasets used by AI algorithms to process electroencephalogram (EEG) signals is scheduled to take effect on September 1, 2027. It sets requirements and evaluation methods for dataset collection, processing, annotation, storage and access.
The aim is to address inconsistent data practices that can make it difficult to compare research results or develop reliable algorithms. If training datasets differ substantially in quality and format, an AI system’s performance may become harder to evaluate and reproduce.
This is particularly important for medical applications, where unreliable signal interpretation could affect a patient’s ability to operate an assistive device.
China, Neuralink and the Global Brain-Tech Race
China’s standardisation push comes as companies worldwide pursue BCI technologies for medical rehabilitation, communication and other applications.
Neuralink, founded by Elon Musk, is among the most prominent companies developing implanted brain-computer interfaces. Chinese companies, including Neuracle, StairMed and NeuroXess, are also working on neural technologies and medical applications. Other firms, such as BrainCo, focus on non-invasive systems and brain-controlled assistive products.
China has supported the sector through industrial policy, research programmes and efforts to develop domestic companies. Establishing standards can strengthen that strategy by giving manufacturers a clearer framework for product development and testing.
International standards may also give Chinese researchers and companies greater influence over how the global industry defines technical concepts and system architecture.
Still, standards leadership does not automatically translate into market leadership. Companies must also demonstrate dependable performance, protect sensitive neural data, secure regulatory approvals and establish viable business models.
What Are the Risks and Challenges?
BCI technology raises questions that go beyond engineering.
Safety and reliability: Implanted systems involve medical and surgical risks. All systems need to be evaluated for their intended use, while performance must remain reliable enough for users to depend on them.
Privacy of neural data: Brain signals can reveal sensitive information about a person’s activity or state. Organizations developing these technologies need robust rules for collecting, storing, accessing and sharing neural data.
Ethical oversight: Researchers and companies must consider informed consent, user autonomy and the possibility of misuse. People using assistive BCIs may be particularly dependent on the reliability and availability of their devices.
Uneven access: Advanced medical BCI systems can require specialised equipment, trained clinical teams and long-term support. High costs could limit access even if technical standards improve.
Standardisation can help create consistent technical practices, but it cannot resolve every ethical, legal or social concern on its own.
The Bigger Picture
China’s BCI standardisation effort shows that competition in emerging technologies is increasingly about shaping the rules as well as developing products. Common frameworks can influence how systems are designed, tested and evaluated, potentially giving the countries and organisations involved an important role in future markets.
The global impact will depend on whether international standards are widely adopted and followed by practical implementation, strong evidence and effective regulation. As BCIs progress from laboratory research toward real-world applications, the ability to establish trust and demonstrate safety may prove as important as advances in decoding brain signals.
