China’s comfortable brain-reading device achieves 94% mind-typing accuracy in day-long use
Chinese researchers have created a comfortable electrode for non-invasive brain-computer interfaces (BCIs) that achieved over 94 per cent accuracy in visual mind-typing tests during day-long use. The gradient electrodes – designed to overcome the current trade-offs of conventional uniformly soft or rigid electrodes – were integrated into a commercial electroencephalogram (EEG) cap and tested…
Chinese scientists have developed a novel, comfortable electrode for brain-computer interfaces (BCIs) that achieved an impressive 94% accuracy in visual mind-typing tests during prolonged use. These gradient electrodes, designed to overcome the limitations of conventional electrodes, were incorporated into a commercial EEG cap and evaluated over a 14-hour period of rest.
Additionally, the electrodes facilitated eight hours of stable EEG brain recordings while a human subject engaged in daily activities, addressing critical challenges for the real-world implementation of non-invasive BCIs. The researchers from Guangxi University, Guangxi Medical University, and Tsinghua University published their findings in the journal NPJ Flexible Electronics, highlighting the potential of these gradient hydrogel electrodes for real-world BCI applications.
This breakthrough could pave the way for widespread use of non-invasive BCIs in daily healthcare, sleep monitoring, and the early detection of conditions like epilepsy.
