To expand the applications of the electroencephalogram (EEG), long-term measurement, a short installation time, and little stress on the participants are needed.In this study, we designed, fabricated, and evaluated an EEG headset with three candle-like microneedle electrodes (CMEs).The user is able to detach and reattach the electrodes, enabling long-term measurement with little stress.
The design of the CMEs was experimentally determined by considering the skin-to-electrode impedance and user comfort.An EEG was successfully measured from areas with a high hair density without any preparation.The installation time ucsb gaucho blue was shorter than 60 s and the electrodes could be detached and reattached.
The headset was designed such that the discomfort caused by its ear pads was higher than that caused by the electrodes.In 1 h experiments, the participants did not feel pain and the detachment of the CMEs was found to improve the comfort level of the participants in most cases.A successful demonstration of the long-term measurement of la rams crop top EEGs while watching a whole movie verified that the developed EEG headset with CMEs is applicable for EEG measurement in a variety of applications.
