Penn State researchers created hair-like device for stable brain monitoring

Researchers have developed a hair-like brain monitoring device for long-term, non-invasive EEG monitoring, offering improved comfort and signal quality. The new device, created by Penn State researchers, uses flexible, hair-like electrodes that attach directly to the scalp, providing stable, high-quality brain signal recordings without skin irritation, unlike traditional methods. The device maintains stable performance for over 24 hours of continuous use. This technology could improve patient comfort and potentially be used in consumer health products. Future plans include a wireless version to increase patient mobility during monitoring.
