The Brain Cube, developed by the Tianjin University Brain-Computer Interface Laboratory, is a non-invasive device weighing 3 grams with a volume of 2 cubic centimeters. It integrates electrodes, an amplifier, a battery, and a wireless transmitter into a compact housing designed to be worn on the scalp under hair.
The device eliminates the need for traditional headsets or caps, allowing for long-term monitoring of brain activity outside laboratory settings. The platform is designed for comfort, enabling continuous use while maintaining data collection capabilities.
Potential applications for the technology include clinical monitoring of brain markers, consumer neuro-gaming, and device control. In education, the system can perform synchronous scanning of multiple individuals to measure cognitive metrics in real time.
The laboratory is also collaborating with government agencies on industrial safety projects. These models aim to monitor operator fatigue, attention levels, and cognitive load during high-risk tasks, providing real-time data for workplace safety management.
