The invention provides a composition for a conductive polymeric material suitable for the production of electrodes for recording electrophysiological signals, such as electrocardiogram (EGG), electromyogram (EMG), electroencephalogram (EEG), etc and signals related to the impedance variation of the body or skin, both deriving from active and passive measures (for example, breathing, electrodermal response, etc.). For this purpose a formulation containing FEDOT and ionic liquids has been developed. The formulation according to the invention can be used generically in the context of detecting bioelectric signals and can be applied on wearable items, in particular in fabric, such as for example garments of different shapes, so as to be in direct contact with the areas of the body subject to detection. The artifacts include diving artefacts, such as watertight suits, and for water sports and submarine surveys, artifacts used in the medical and health sector such as plasters, elastic support bands and adhesive support bands and textile articles, including special fabrics such as bioceramics.
