Tianjin University releases a 3-gram brain-signal recorder that sits hidden in the hair
Tianjin University's Haihe Laboratory of Brain-Computer Interaction and Human-Machine Integration and its partner Shengong Diting (Tianjin) Technology announced the Shengong Xumi Brain Cube on 30 September 2026, a non-invasive EEG device weighing 3 grams and measuring about 2 cubic centimetres, with electrodes, circuitry, battery and wireless link in one unit fixed to the scalp among the hair. It records at 1,000 samples a second for 8 to 10 hours, and its developers call it the smallest and lightest non-invasive brain-computer interface system yet made. The lab says it is building safety management models around the device for workers in China's licensed high-risk trades, with guidance from special-operations and emergency-management departments. China's national BCI plan names hazardous materials, nuclear, mining and power as industries to pilot the technology first.
