Key result
Novel two-channel circuitry and mathematical model maximize non-contact ECG SNR with smaller air-gaps.
Why the study?
Non-contact ECG electrodes avoid skin irritation and can be worn over clothing, but motion artefacts from changing sensor-body impedance remain a major challenge.
A novel two-channel circuitry and mathematical model for non-contact ECG sensors improves Signal to Noise Ratio by mitigating motion artefacts, particularly with smaller air-gaps and higher channel area ratios.

May enhance non-contact ECG signal quality in motion settings; leaves open human validation before clinical use.
Kalra et al. (2024) studied this question. Two-channel circuitry and mathematical model was evaluated on Signal to Noise Ratio (SNR). A novel two-channel circuitry and mathematical model for non-contact ECG sensors achieved the highest Signal to Noise Ratios with smaller air-gaps and higher ratios of channels' areas.
