Textile Electrodes for Electrocardiogram Monitoring

Abstract Electrocardiogram (ECG) monitoring is crucial for early diagnosis and timely treatment of cardiovascular diseases which are the major cause of global death, and it is of great significance but a long‐standing challenge to acquire the stability of signal quality while maintaining high comfort during ECG monitoring over a long time. Textile electrodes offer strong potential for applications in the long‐term monitoring of ECG signals due to gel‐free and dry characteristics compared with existing wet silver/silver chloride (Ag/AgCl) gelled electrodes. Therefore, the last few years have witnessed the rapid development of textile ECG electrodes which are further accelerated by the booming researches on wearable electronics. Herein, a review of recent advances in textile electrodes for ECG monitoring with a focus on advanced material designs and construction technologies is presented. First, comprehensive considerations of ECG monitoring with textile electrodes are provided. Subsequently, the fabrication technologies for high‐performance textile ECG electrodes are highlighted. Finally, particular emphases are placed on the current challenges and future opportunities of textile electrodes for ECG monitoring.
