A 3-gram brain-computer interface unveiled in Tianjin sits on the scalp and disappears between strands of hair. Tianjin University and Shengong Diting (Tianjin) Technology call the non-invasive system Shengong · Xumi · Brain Cube. IT Home recorded the announcement on October 4, 2026: under 2 cubic centimeters, and a claim that it is the smallest and lightest non-invasive system announced so far.
What happened?
The project comes from the Haihe Laboratory of Brain-Computer Interaction and Human-Machine Integration. Instead of a cap, helmet or headband, it packs EEG electrodes, circuitry, a battery and wireless transmission into a module fixed to the skin. EEG is a recording of the brain’s electrical activity from the outside, without surgery.
The core argument is near-invisible wear. Non-invasive gear is often bulky. A 3-gram module, in the authors’ view, opens a path to medicine, consumer products and industry. That is still an intended use, not a shelf product with a published price.
What the system claims
IT Home says core indicators meet the Chinese standard GB 9706.226-2021 for EEG equipment. Battery life is 8 to 10 hours at 1,000 Hz, a high rate for long tasks. The report does not publish a price, a retail date or the number of channels.
The lab also started a project with companies and universities, guided by agencies for special operations and emergency management. The stated focus is a safety model using a brain-computer interface and wearables for workers in special tasks. That is applied research, not large-scale validation.
Why it matters
Implantable interfaces require surgery. The non-invasive path is easier to test and, in principle, easier to accept outside hospitals. The historical bottlenecks are a weak signal and discomfort. A 3-gram module does not by itself solve signal quality, but it lowers the barrier to daily use if capture stays stable outside the lab.
Independent accuracy data, comparisons with clinical caps and commercial approval are still missing. What is confirmed is the announcement, the size, the weight, the cited battery life and the intended use. The original report is on IT Home.
