China’s gradient-electrode EEG cap hits 94% mind-typing accuracy

A non-invasive brain-reading device featuring gradient electrodes has achieved a 94 percent mind-typing accuracy during day-long use. Integrated into a commercial EEG cap, the electrodes enabled 14 hours of resting tests and eight hours of stable EEG recordings during daily activities, overcoming key barriers to real-world deployment for brain-computer interfaces.
