1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsChina’s Brain Talker chip was presented in 2019 as hardware for decoding neural signals in brain-computer interfaces (BCIs)—not as a device that can read any thought on demand. The report described an intended way to distinguish weak electrical signals from the brain and process them for computer interaction, but supplied no measured performance results.
What was Brain Talker?
In a June 3, 2019 report, Futurism said Tianjin University and China Electronics Corporation had developed Brain Talker, also called the Brain-Computer Codec Chip (BC³). The chip was intended for use in brain-computer interfaces, systems that translate neural activity into commands or other machine-readable outputs.

Tianjin University researcher Ming Dong described the challenge as separating neural signals from background noise. The report quoted him saying the chip could “discriminate minor neural electrical signals and decode their information efficiently.” That describes the developers’ claimed purpose; the article did not provide test results that independently establish how well it did so.
What does a BCI “read”?
A BCI reads signals, not thoughts in the unrestricted sense implied by “mind-reading.” It records activity from the nervous system and uses processing and decoding methods to map relevant patterns to a defined task, such as selecting a command. What a system can infer depends on how signals are acquired and what the decoder is designed and tested to recognize.

- Flexible Power and Project Setup: Includes a 9 V, 1 A power supply, breadboard power module, 9 V battery and USB cable to support controller, breadboard and module experiments without sourcing basic setup accessories separately
So the 2019 headline is best understood as shorthand for a chip designed to help a BCI process neural signals. The report does not show that Brain Talker could reveal private thoughts, decode arbitrary inner speech, or understand a person without a task-specific setup.
What did the 2019 report establish—and what did it not?
The report presented Brain Talker as an effort to make BCIs more portable, wearable, and accessible. Those were stated aims, not evidence that the chip became a consumer product or achieved clinical success. The article did not establish technical specifications, measured speed or accuracy, clinical testing, regulatory status, sales, or broad adoption.

That absence in the report is not proof that no subsequent work occurred. It means the specific claims above cannot be confirmed from that account. Without later validation or deployment evidence, Brain Talker should be described as a reported BCI chip development, not a demonstrated general-purpose mind-reading device.

- Medical-device EEG data: A September 17, 2026 Xinhua report said a standard covering quality requirements and evaluation methods for EEG datasets used by AI algorithms in BCI medical devices would take effect September 1, 2027. That is a separate standard, not a Brain Talker performance assessment. Xinhua report hosted by the Chinese Embassy in Bolivia.
- Separate research examples: A September 2026 Shanghai government report described SynSense’s Rigi neural-signal acquisition chips for medical and neuroscience research; a Chinese Academy of Sciences institute separately reported Lingyu, an implantable BCI brain-to-sentence decoding framework using sEEG electrodes and a task-specific language model. Neither report identified a link to Brain Talker. Shanghai report on Rigi; CAS report on Lingyu.
What would demonstrate that the chip worked?
A meaningful assessment would need more than a stated ability to decode weak signals. Useful evidence would identify the signal-acquisition method, the tasks tested, the number and characteristics of participants, measured accuracy and speed, comparison conditions, and whether results were independently replicated. For claims about real-world use, readers would also need evidence of safety, regulatory status where relevant, and actual deployment. The 2019 report does not supply these details.
