Overview

The OxyZen device provides real-time feedback on your mindfulness state by collecting and analyzing biological signals such as EEG, heart rate, and SpO2.

Biological Signal Data

When users wear the OxyZen device, it collects and provides real-time feedback on their biological signal data, including EEG, heart rate, and SpO2.

Data	Description
Electroencephalogram (EEG)	Single-channel EEG data with a sampling rate of 256 Hz, measured in μV
Heart Rate (HR)	Ranges from 30 to 220 bpm
Blood Oxygen Saturation (SpO2)	Ranges from 70% to 100%

TIP

To ensure accurate data collection, make sure the electrodes maintain good skin contact. If your skin is dry, wipe your forehead with a damp cloth.

The EEG data collected is the potential difference between the Fp1 and Fp2 electrodes. After the signal stabilizes, the value should be within the range of ±120 μV.

Algorithm Data

• The Calmness and Awareness values are SDK algorithm outputs derived from EEG data. They are application metrics, not clinical measurements.
• The Meditation Value is derived from the Calmness and Awareness values.

Data	Description
Meditation Value	Range: [0~100], Active/Peaceful/Relaxed/Deep mindfulness
Calmness Value	Range: [0~100], Higher values represent greater calmness
Awareness Value	Range: [0~100], Higher values represent greater awareness
Drowsiness Value	Range: [0~100], Higher values represent greater drowsiness
Sleep Stage	WAKE/REM/LIGHT/DEEP
