Objective: The main task of this work consists in an obtaining polarizable, dry mode, of bio-impedance sensors for non-invasive ECG monitoring, that work without any skin preparation or gel use, in two constructive models, based on conductive organic polymer polypyrrole and polypyrrole with Ag nanoparticles (NP), as sensitive materials. Methods: The polypyrrole was synthetized by chemical oxidative polymerization using FeCl3 as oxidant agent. For sensors fabrication two technological variants…
