How HRV Monitoring Works
The science behind real-time stress detection on your wrist.
What Is HRV?
Heart Rate Variability measures the time variation between consecutive heartbeats. Higher HRV indicates better stress resilience and parasympathetic nervous system activity. Lower HRV signals stress, fatigue, or illness.
Medical-Grade PPG Sensor
AuraWave uses a photoplethysmography (PPG) sensor with green LED technology to measure blood volume changes through your skin. Our sensor achieves clinical-grade accuracy comparable to chest-strap monitors.
AI-Powered Baseline Learning
Our proprietary algorithm builds a personalized HRV baseline over your first 72 hours of wear. It learns your unique patterns — sleep, exercise, work stress — to detect anomalies with precision.
Real-Time Stress Detection
When your HRV drops significantly below your personal baseline, AuraWave's AI identifies a stress event within 3 seconds. This triggers the Auto Stress Relief system automatically.
Continuous Trend Analysis
Beyond real-time detection, AuraWave tracks your HRV trends over days, weeks, and months. The app provides weekly reports showing your stress patterns, recovery quality, and overall nervous system health.
