Diamond/Porous Titanium Nitride Electrodes With Superior Electrochemical Performance for Neural Interfacing.

ABSTRACT: Robust devices for chronic neural stimulation demand electrode materials which exhibit high charge injection (Q _inj) capacity and long-term stability. Boron-doped diamond (BDD) electrodes have shown promise for neural stimulation applications, but their practical applications remain limited due to the poor charge transfer capability of diamond. In this work, we present an attractive approach to produce BDD electrodes with exceptionally high surface area using porous titanium nitride (TiN) as interlayer template. The TiN deposition parameters were systematically varied to fabricate a range of porous electrodes, which were subsequently coated by a BDD thin-film. The electrodes were investigated by surface analysis methods and electrochemical techniques before and after BDD
