Study of Common Mode Noise Cancellation Circuit with Photo-Resistor for Wearable ECG
Mutsumi Noro, Daisuke Anzai, Jianqing Wang (NIT) EMCJ2016-103
Abstract (in Japanese) (See Japanese page) 
(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.
