Our full-stack biometric solution, decomposed into its core sensing modules. Evaluate the data streams available for your platform or product.
Our architecture integrates PPG, an infrared thermopile, and a 3-axis MEMS accelerometer to continuously capture physiological signals. Proprietary algorithms filter motion artifacts and perfusion noise, extracting clean waveforms for precise measurement of heart rate, HRV, and SpO₂. A dual-wavelength PPG sensor (green & infrared LEDs) works with our noise-cancellation algorithm, achieving a 94.5% correlation coefficient against clinical-grade references. Skin temperature is tracked by a high-precision (±0.1°C) thermopile sensor, black-body calibrated for consistency across environments and wear positions. All data is processed locally, encrypted, and structured for seamless integration into enterprise health platforms.







Our system decodes sleep architecture by continuously monitoring Heart Rate Variability (HRV), body movement, and subtle temperature changes throughout the night. The proprietary algorithm fuses data from the 3-axis accelerometer and autonomic nervous signals captured by the PPG sensor to accurately distinguish between wake, light sleep, deep sleep, and REM stages. This provides a quantitative basis for assessing sleep quality and recovery. The core algorithm utilizes a time-series model trained on extensive datasets, demonstrating high sensitivity in detecting periodic limb movements and sleep interruptions. All analysis is performed on-device to ensure data privacy.









The system captures subtle rhythmic changes in Heart Rate Variability (HRV) through high-frequency PPG sensors, utilizing it as a core biomarker to assess autonomic nervous system balance and stress load. Our professionally tuned algorithm integrates HRV time-domain and frequency-domain analysis with activity and sleep data. This fusion enables the calculation of a real-time stress index and the identification of long-term stress trends and emotional recovery patterns. By establishing a personalized physiological baseline, the system can distinguish between physiological stress and psychological emotional fluctuations.

While most smart rings are passive data collectors, COMI is active. Our precision linear motor delivers intelligent, context-aware feedback that connects you to what matters—without ever looking at a screen.

Unlike traditional rotor motors, our linear motor delivers precise, programmable vibrations with millisecond response time. This allows for distinct patterns you can recognize by feel alone.
Battery performance varies with your activity level. Expect 4-6 days of power with standard notification settings, or roughly 3-4 days for heavy users with frequent haptic feedback.
Call & alarm: 3 vibrations. Notifications: 1 vibration. You'll learn to distinguish important alerts from casual notifications without checking your phone—keeping you present in the moment.
COMI vibrates to alert you of potential health issues whenever your heart rate, body temperature, or blood oxygen levels deviate from your personalized thresholds.
