Headband with 4 soft movable electrodes, PPG sensor, gyroscope, and accelerometer
The headband is soft and flexible, it has an adjustable fastener for any head size
The device has 4 EEG channels and a reference electrode, as well as grounding on the forehead area. Each channel has 25 pins, which allows a bigger contact area and a more stable signal reception
Pins are dry and spring-loaded: they will not break, crack, or wear out. They do not press the head uncomfortably, and they can work even through hair
The electrodes are gold-coated, and it is the best way to collect EEG data in the dry method
