Hair-Thin 3D-Printed Electrode Revolutionizes EEG

Researchers at Penn State have developed a revolutionary 3D-printed electrode, as thin as a human hair, offering significantly more reliable brain activity monitoring than traditional EEG methods. This gel-less, 'stick-and-play' device remains securely attached for 24 hours, even during exercise and showering, minimizing motion artifacts and enhancing signal quality. Its improved comfort and reliability open doors for consumer health applications, brain-computer interfaces, and advancements in assistive technologies.
