Revolutionary 3D-Printed Hair-like Electrodes Enable 24/7 EEG Monitoring
2025-05-08
Researchers at Penn State have developed a groundbreaking 3D-printed EEG electrode that mimics human hair and uses a bioadhesive ink to adhere directly to the scalp without gels. This lightweight, flexible, and stretchable electrode stays in place even during activities like combing hair or wearing a hat, significantly improving signal quality and enabling long-term monitoring. Performing comparably to gold standard electrodes, it maintains reliable contact for over 24 hours without signal degradation, eliminating inconsistencies from electrode repositioning. The discreet design improves patient comfort, paving the way for more convenient and reliable chronic EEG monitoring. Future work aims to make the system wireless.
