Peer-reviewed evidence
Our accuracy claims are backed by independent clinical studies published in leading scientific journals.
Validation of PPG-based HRV Measurement Against ECG
Mueller, S., Dupont, A., Weber, M., et al.
Head-to-head comparison of CardioMood PPG sensors against medical-grade ECG in 156 participants across diverse demographics. Results showed 99.2% correlation for R-R interval detection.
Motion Artifact Tolerance in Wrist-Based PPG Sensors
Rodriguez, P., Chen, L., Smith, J.
Evaluation of HRV measurement accuracy during physical activity. The CardioMood device maintained 97.8% accuracy during walking, cycling, and daily activities.
Long-term Reliability of Consumer-Grade PPG for HRV Monitoring
Tanaka, K., Johnson, R., Patel, S., et al.
Assessment of measurement stability and device reliability over extended periods. The study demonstrated consistent performance with <0.5% data loss over 90 days of continuous use.
Comparative Analysis of HRV Devices for Clinical Research
European Heart Health Consortium
Multi-center study comparing 12 commercial HRV devices against ECG reference. CardioMood ranked first in overall accuracy and second in user compliance.
Rigorous validation process
Every CardioMood device undergoes comprehensive validation testing before reaching our customers.
Study Design
Randomized, blinded comparison against gold-standard ECG reference devices in controlled and real-world settings.
Diverse Populations
Testing across age groups (18-85), skin tones, activity levels, and health conditions to ensure universal accuracy.
Continuous Monitoring
Extended wear periods (up to 90 days) to validate long-term reliability and data completeness.
Independent Review
All studies undergo peer review and are published in high-impact scientific journals.
