Outline of Final Research Achievements

This work presents a patch-type EEG sensor using biocompatible and stretchable electrode sheet. The system has advantage of installation in measuring EEG signals. The patch-type EEG consists of stretchable electrode sheet and wireless sensor system. The electrode sheet is developed by screen printing technique and on-demand fabrication. The sheet is also disposable to ensure the safety of subjects. The system was optimized to fit the stretchable electrode sheet.
