Device
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. XL stripes are available upon request.
The device has 4 EEG channels, a reference electrode, and grounding on the forehead area. Each channel has 25 pins, which allows for a bigger contact area and a more stable signal reception.
Pins are designed to be dry and spring-loaded, so they will not break, crack, or wear out. They do not cause discomfort on the head and perfectly work through hair.
The electrodes are gold-coated, and it is the best way to collect EEG data in the dry method.
Continuous work time: 8 hours
EEG
EEG is a method for reading brain electrical activity. The device collects raw data and processes in into understandable metrics
4 EEG channels: О1, О2, T3, Т4
Works with the following brain rhythms: Theta, Alpha, SMR, Beta
Sampling rate: 250 Hz
Measured voltage range: ±0.4 V
PPG
PPG is a way of measuring heart rate. It makes other indexes more clear
PPG signal measurement sampling rate: 100 Hz
Angular speed
Angular speed assists in eliminating movement artifacts. Quick head movements or nods are not interpreted as artifacts by the device.
Angular velocity is measured along three orthogonal axes
Range of the angular speed measured: ±250; ±500; ±1000; ±1200; ±2000 degree/second
Acceleration is measured along three orthogonal axes
Measured acceleration range: ±2; ±4; ±8; ±16 g
Supported OS:
iOS, macOS, Windows, Android
