Key Features and Functionalities

Advanced Sensor Suite

The Q-Stat is equipped with a comprehensive array of sensors for precise health and environmental monitoring:

• Photoplethysmography (PPG): Monitors blood flow to derive heart rate, heart rate variability, respiration rate & blood oxygen saturation (SpO2). The Q-Stat incorporates Galvanic skin response and color sensing into the pulse oximeter for improved SpO2 accuracy across diverse skin types.
• Inertial Measurement Unit (IMU): A dynamically self-calibrated accelerometer, gyroscope, and magnetometer accurately track movement, orientation, and position. Through patented technology, the IMU is combined with the PPG sensor for state-of-the-art motion artifact removal.
• Electrocardiogram (ECG): Monitors heart activity to detect conditions like atrial fibrillation, supporting cardiovascular health assessment.
• Galvanic Skin Response (GSR) & Bioimpedance (BioZ): Measures skin conductance and tissue impedance for stress monitoring and advanced physiological insights.
• Temperature Sensors: Includes a skin temperature sensor for body temperature monitoring and an ambient temperature sensor to contextualize environmental effects on health.
• Proximity Sensor: Enhances device functionality by detecting wear status, optimizing power usage and data accuracy.
• 14-Channel Multispectral Sensor: Captures reflectance across 14 discrete wavelengths, enabling precise tissue characterization, hydration assessment, oxygen saturation profiling, and pigment analysis. It significantly enhances detection of physiological and environmental changes—such as cyanosis, inflammation, or dehydration—through detailed spectral signatures.

Sensor Fusion and AI Analytics

The Q-Stat leverages proprietary sensor fusion algorithms to integrate data from its IMU, PPG, ECG, GSR, BioZ, temperature, and 14-channel multispectral sensors. This fusion enables a deeper, more nuanced understanding of the user’s physiological state. The multispectral data enhances traditional optical measurements by providing spectrally resolved information that improves SpO2 estimation under challenging conditions, refines tissue oxygenation metrics, and supports early identification of dermatological or circulatory anomalies.

Combined with advanced AI algorithms and signal processing, the Q-Stat delivers highly accurate and context-aware health metrics. This integrated analysis produces real-time, actionable health insights, enabling early detection of critical medical events, improved stress and fatigue monitoring, and personalized wellness recommendations with enhanced precision.
