可穿戴心电图（ECG）在日常医疗保健应用中备受关注，而人体通信（HBC）技术在使ECG的感测电极也用于通过人体传输方面提供了明显的优势。然而，考虑到日常生活中的实际使用，期望电极与人体非接触。在这封信中，作者讨论了基于HBC的可穿戴ECG中的ECG电路结构，以消除采用非接触电容耦合电极时的共模噪声。通过实验结果的比较，表明作者提出的第三电极直接接地的电路结构，可以提供与通常的右腿驱动电路相似的共模噪声抑制效果，并具有足够好的心电信号采集性能。
Wearable electrocardiogram (ECG) is attracting much attention in daily healthcare applications, and human body communication (HBC) technology provides an evident advantage in making the sensing electrodes of ECG also working for transmission through the human body. In view of actual usage in daily life, however, non-contact electrodes to the human body are desirable. In this Letter, the authors discussed the ECG circuit structure in the HBC-based wearable ECG for removing the common mode noise when employing non-contact capacitive coupling electrodes. Through the comparison of experimental results, they have shown that the authors' proposed circuit structure with the third electrode directly connected to signal ground can provide an effect on common mode noise reduction similar to the usual drive-right-leg circuit, and a sufficiently good acquisition performance of ECG signals.
