A Wearable Heart Rate Monitoring System Based on Over-Ear Headphones
Modular over-ear headphone system with dry-contact conductive textile electrodes achieving 4.4% R-R interval detection error for continuous heart rate monitoring.
Abstract summary
Over-ear headphones were modified with dry-contact conductive textile electrodes and custom ear pads to acquire ECG-suitable signals during wear. The system achieved 4.4% R-R interval detection error for continuous heart rate monitoring in testing.
Key findings
- Feasibility of headphone-form-factor cardiac monitoring
- Modular pad and electrode design for textile dry contacts
- Quantitative R-R error metric suitable for continuous heart rate monitoring
