Abstract:

Aiming at the problems that Ag/AgCl gel electrode is not suitable for long-term monitoring and the single lead for wearable electrocardiogram (ECG) device is insufficient for precise examination, a seven-lead wearable ECG monitoring system based on graphene fabric electrode was designed. The system was made of four parts, i.e. the cotton/T400 blended high-elastic ECG suit, a graphene fabric electrode, a seven-lead ECG acquisition terminal, and an APP for data display. The continuous work hours, continuous wearing signal quality and multiple usage scenarios of the system were measured for analysis. The test results show that the SNR (signal/noise ratio) of ECG signal is about 29.8 dB after wearing the graphene fabric electrode for 7 days continuously. The device with a 250 mA·h lithium battery can be used for a maximum of 5 days. It has high reliability, accuracy and wearability in multiple test scenarios of resting, walking, jogging and resting spontaneous sweating. To some extent, it has great potential for continuous remote monitoring.

Key words: graphene fabric electrodes, smart textiles, seven-lead, wearable electrocardiogram monitoring terminal, low energy, cotton/T400 blended high-elastic electrocardiogram suit
