| Abstract(in English) | In recent years, wearable devices that can detect disease in advance by checking vital data such as body temperature, blood pressure, and electrocardiogram while living outside the hospital have been attracting attention. However, if the contact states of the vital data detection electrodes are different from each other, an imbalance occurs between the contact resistances of the detection electrodes. The imbalance converts common mode noise induced in the input of vital sensor by external electromagnetic field such as commercial power supply or wireless power transmission into differential mode interference voltage to make the detection quality of the vital signal degrade. In this study, a circuit was proposed to cancel the imbalance of the contact resistance in order to reduce the noise in electrocardiogram signal. A simulation experiment was conducted to verify the noise reduction effect for common mode noise input to the sensor electrodes using the proposed circuit. Moreover, the noise reduction effect was verified by experiment also for the electrocardiographic signal with common mode noise superimposed. |
