Abstract (EN): Titanium nitride (TiNx) thin films were deposited by PVD, in a wide range of compositions (0 < x < 0.99), on polycarbonate (PC) substrates, aiming at studying their potential application as bio-electrodes. The electrochemical study of the TiNx films, performed in an isotonic sodium chloride solution, proved the very good chemical stability of all films in salt solution conditions. On the other hand, the electrochemical noise analysis showed that the electrical noise generated at the stoichiometric TiN/electrolyte interface is of the same magnitude as that generated by the traditional Ag/AgCl electrodes.
