Splet28. feb. 2024 · However, our recent electrochemical in vitro investigations revealed that the sweat artifact tolerance of an EEG electrode can be improved by utilizing an appropriate Ag/AgCl ink. Here we have investigated in vivo electrode-skin impedances and the quality of EEG signals and interference due to sweating in the population of 11 healthy volunteers. SpletTo overcome this shortcoming, we recently introduced a self-applicable facial electrode set with screen-printed EEG electrodes. However, one remaining challenge in overnight EEG measurements is the presence of a low-frequency sweat artifact commonly occurring in sleep recordings.
