Real-time monitoring of chronic diseases such as cardiovascular diseases (CVDs) requires biopotential electrodes functioning over a long period without degrading recorded ECG signal quality. However, conventional conductive gel-based Ag/AgCl electrodes dehydrate over time gradually deteriorating the signal quality. Here, we fabricated graphene-based flexible textile electrodes for biosignal detection suitable for wearable devices. These electrodes are highly conductive and establish a low impedance contact with the skin. The recorded ECG signal signal-to-noise ratio (SNR) reaches up to 39.3 dB, 58% higher than the commercial Ag/AgCl electrode. The produced electrodes are flexible, therefore, adhere better to the skin at different anatomical positions of the body. Finally, the superhydrophobic property allows them to be used repeatedly after washing without compromising the quality of the ECG signal.

Abstract
Real-time monitoring of chronic diseases such as cardiovascular diseases (CVDs) requires biopotential electrodes functioning over a long period without degrading recorded ECG signal quality. However, conventional conductive gel-based Ag/AgCl electrodes dehydrate over time gradually deteriorating the signal quality. Here, we fabricated graphene-based flexible textile electrodes for biosignal detection suitable for wearable devices. These electrodes are highly conductive and establish a low impedance contact with the skin. The recorded ECG signal signal-to-noise ratio (SNR) reaches up to 39.3 dB, 58% higher than the commercial Ag/AgCl electrode. The produced electrodes are flexible, therefore, adhere better to the skin at different anatomical positions of the body. Finally, the superhydrophobic property allows them to be used repeatedly after washing without compromising the quality of the ECG signal.File | Dimensione | Formato | |
