This study presents a novel type of wet electrode material for electrophysiological monitoring based on a conductive aerogel film. The electrode material incorporates cellulose nanocrystal and fiber as a biocompatible polymer and multi-walled carbon nanotube as a conductive filler. The wet aerogel film presents suitable mechanical flexibility and a high water absorption due to the porosity of the film and hydrophilicity of the base polymer allowing it for effective wet electrode applications. The electrical impedance range of the fabricated aerogel electrodes is within the range of use for various electrophysiological monitoring purposes such as electrocardiography (ECG) and electroencephalography (EEG). read more
