Non-invasive brain-computer interface weighing 3 grams

Researchers from Tianjin University have unveiled a non-invasive brain-computer interface weighing just 3 grams.

Bulky helmets and headbands are being replaced by miniature devices hidden in hair.

The new device, the 'Shengong Xumi Brain Cube', has a volume of 2 cm³ and integrates EEG electrodes, a battery, and a wireless communication module. It adheres to the scalp, allowing it to be worn constantly without looking different from a regular hair clip.

Unlike cumbersome laboratory helmets, its compactness ensures quality skin contact and enables the accumulation of big data for artificial intelligence.

Developers claim capabilities for long-term monitoring of brain activity, neurofeedback, and sleep analysis.

The device supports:

• controlling gadgets and games via BCI
• sleep quality analysis
• medical health monitoring
• simultaneous reading of multiple people's brain activity

Particular interest lies in applying this technology in field conditions to monitor special forces units.

Its small size and high contact density make the device a promising alternative to implants, offering a non-invasive way to obtain detailed neural data.
