Heart Monitoring Garments Using Textile Electrodes for Healthcare Applications

We measured the electrical activity signals of the heart through vital signs monitoring garments that have textile electrodes in conductive yarns while the subject is in stable and dynamic motion conditions. To measure the electrical activity signals of the heart during daily activities, four types of monitoring garment were proposed. Two experiments were carried out as follows: the first experiment sought to discover which garment led to the least displacement of the textile electrode from its originally intended location on the wearer’s body. In the second, we measured and compared the electrical activity signals of the heart between the wearer’s stable and dynamic motion states. The results indicated that the most appropriate type of garment sensing-wise was the “cross-type”, and it seems to stabilize the electrode’s position more effectively. The value of SNR of ECG signals for the “cross-type” garment is the highest. Compared to the “chest-belt-type” garment, which has already been marketed commercially, the “cross-type” garment was more efficient and suitable for heart activity monitoring.
