PEDOT: PSS treated cotton-based textile dry electrode for ECG sensing

Abstract

Reliable extraction of physiological signals from human skin is essential information for health monitoring, preventive care, and treatment. Wearable bioelectronics advancements that are directly placed on the epidermis surface offer a promising future biopotential sensing option. Wearable health-monitoring systems should be comfortable, stigma-free, and capable of producing high-quality data. Wearable textile electrodes for biopotential sensing are a promising candidate for long-term health monitoring to overcome the drawbacks of wet and metal electrodes. This work proposes a cotton-based textile dry electrode for ECG monitoring via the treatment of prepared conductive ink by Poly(3,4-ethylenedioxythiophene) (PEDOT): Poly (styrene sulfonate) (PSS) and DMSO. These electrodes give excellent quality ECG signals without any skin irritation. The ECG is monitored by a portable self-designed low-cost Arduino-based device and validated by a standard ECG monitoring system. The electrode offers high skin compatibility and good signal quality, which are prominent features for cardiorespiratory monitoring.
