Low-Noise and Cost-Effective Active Electrodes for Dry Contact ECG Applications
Active dry-contact ECG electrodes for wearables showed 4.7 dB higher SNR than commercial electrodes on low-amplitude signals.
Abstract summary
Prototype active dry-contact electrodes targeted wearable applications such as headphones and glasses. On low-amplitude signals, prototypes demonstrated 4.7 dB higher SNR than selected commercial dry electrodes, with emphasis on cost-effective manufacturing.
Key findings
- Active front-end improves SNR on dry, low-amplitude ECG
- Applicable to headphone and wrist wearable form factors
- Cost-conscious BOM suitable for prototype iteration
