Common Mode Noise Cancellation for Electrically Non-Contact ECG Measurement System on a Chair

摘要: Electrically non-contact ECG measurement system on a chair can be applied to number of various fields for continuous health monitoring in daily life. However, the body is floated electrically this due capacitive electrodes and very sensitive external noises or motion artifacts which affect as common mode noise. In paper, driven-seat-ground circuit similar driven-right-leg proposed reduce The analysis equivalent performed output signal waveforms are compared between with ground. As results, improves significantly properties fully negative feedback
