China’s “Brain Talker” chip was presented in 2019 as a component for brain-computer interfaces (BCIs), designed to process neural electrical signals—not as a device that can freely read a person’s thoughts. The available report describes its intended function but gives no measured performance results or evidence of clinical or consumer deployment.
What was the Brain Talker chip?
Brain Talker, also called the Brain-Computer Codec Chip or BC³, was reported by Futurism on June 3, 2019. The article attributes its development to Tianjin University and China Electronics Corporation. It describes a chip intended to support brain-computer interfaces by processing neural electrical signals.
Tianjin University researcher Ming Dong said the chip could distinguish weak neural signals from background noise and decode their information efficiently. That is a claim about the chip’s intended capability, as quoted by Futurism from a university press release; the report does not provide independent test results or a performance benchmark.
What does “mind-reading” mean in this story?
Here, “mind-reading” is headline shorthand for decoding neural activity into information a computer can use. A BCI captures signals from the nervous system and processes them for a defined task or output. That is not the same as unrestricted access to someone’s private thoughts: the 2019 account does not show Brain Talker interpreting arbitrary thoughts or revealing everything a person is thinking.
#1 Best Overall
- Real-Time EEG Neurofeedback Headband for Brainwave Monitoring: Monitor your brain activity in real time using advanced EEG sensors. Track key brainwave patterns such as alpha, beta and theta waves to understand how your brain responds during meditation, focus sessions, relaxation and sleep preparation.
- Smart App with Guided Meditation & Brain Training – No Subscription Fees: The companion app offers guided meditation and neurofeedback exercises with real-time brainwave feedback. As your mind calms and focus sharpens, visuals and sound become clearer, helping you practice mindfulness, enhance focus, improve sleep, and train mental control.
- Track Your Brain Training Progress: The app records your sessions and brainwave data, letting you monitor meditation duration, focus levels, and training history. Download your data freely to track progress and understand your brain performance.
- Train Focus and Calmness with Real-Time Neurofeedback: Turn brain activity into meaningful feedback that guides your mind toward deeper calm and concentration. Neurofeedback training helps make meditation more effective while strengthening awareness, focus and relaxation.
- Soft Hydrogel Sensors for Better Comfort & Signal Stability: Flexible hydrogel skin-contact sensors adapt naturally to your forehead, improving comfort and maintaining stable signal transmission. The low-impedance hydrogel interface enhances EEG signal quality for more reliable brainwave analysis.
What the 2019 report does—and does not—establish
- Established in the report: Brain Talker/BC³ was presented as a BCI-focused chip developed by Tianjin University and China Electronics Corporation, with a stated role in signal discrimination and decoding.
- Not established in the report: detailed technical specifications, measured accuracy or speed, clinical testing, regulatory status, commercial availability, or broad adoption.
The absence of those details in that report does not prove that no later testing or deployment occurred. It means the report alone cannot substantiate such claims.
China’s later BCI developments are separate context
Subsequent Chinese policy and research activity shows broader development of the field, but the sources below do not identify these initiatives or projects as successors to Brain Talker.

Government targets and standards
A seven-department policy opinion published on China’s government portal on August 7, 2025, set targets for 2027 and 2030 and named areas for development including neural acquisition and processing chips, communications chips, electrodes, decoding software, and integrated devices. These are policy goals, not evidence that the targets have been achieved or that Brain Talker advanced toward them. Read the policy opinion.
China’s standards catalogue lists GB/T 47023-2026, a BCI reference architecture standard published January 28, 2026, and effective August 1, 2026. Separately, a September 17, 2026 report on a National Medical Products Administration standard says it covers quality requirements and evaluation methods for EEG datasets used by AI algorithms in BCI medical devices; it is scheduled to take effect September 1, 2027. These standards address the field broadly, not Brain Talker specifically.

Separate research examples reported in 2026
A Shanghai municipal report dated September 14, 2026, said SynSense showcased its Rigi series of neuromorphic sensing-computing integrated neural-signal acquisition chips for medical and neuroscience research, describing them as a hardware foundation for invasive BCI devices. The report does not connect Rigi to Brain Talker. Read the Shanghai report.
A Chinese Academy of Sciences institute report dated September 16, 2026, described Lingyu, an implantable BCI brain-to-sentence decoding framework using sEEG electrodes and a task-specific language model. It is presented as a multi-institution research effort, not as a continuation of Brain Talker. Read the institute report.

Brain Talker was introduced as a specialized chip intended to help a BCI process neural signals. The “mind-reading” label should not be taken literally: the cited 2019 account describes signal decoding, not unrestricted thought access, and does not establish how well the chip performed or whether it reached clinical or commercial use.
