This paper reports the EEG-Hat, the hat-type EEG device with candle-like dry microneedle electrodes. Current wearable EEG devices have two major problems; 1) no adjustability to every participant and 2) no ability to measure EEG at hairy part. If these problems are solved, health care technologies in daily life will be developed drastically. The EEG-Hat potentially solves these problems. This device can adjust the electrodes to different size and shape of human head. This device has shutter-like structures to separate hair, so using this device, it is possible to measure EEG without separating hair by hand. First, we quantified the force to press the electrodes and the amount of separating hair. Then, the EEG-Hat fabricated based on the findings successfully measured EEG from 3 hairy parts without manual separation.
