| Abstract(in English) | Wearable electrocardiogram (ECG) is attracting much attention for monitoring heart diseases in healthcare and medical applications. However, an imbalance usually exists between the contact resistances of sensing electrodes, so that a common mode noise caused by external electromagnetic field can be converted into the ECG detection circuit as a differential mode interference voltage. In this study, after explaining the mechanism of how the common mode noise is converted to a differential mode interference voltage, we propose a circuit with cadmium sulfide (CdS) photo-resistors for canceling the imbalance between the contact resistances and confirm its validity by simulation experiment. As a result, we found that the interference voltage generated at the wearable ECG can be effectively reduced to a sufficient small level. |
