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 crystal beaded candle holder 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 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 tata funko pop the long-term measurement of EEGs while watching a whole movie verified that the developed EEG headset with CMEs is applicable for EEG measurement in a variety of applications.
