Electrochemical noise properties of different electrode materials in different electrolytes

  • Conference paper

Part of the book series: IFMBE Proceedings ((IFMBE,volume 13))

Abstract

Signal-to-noise ratio of a biopotential measurement system is determined not only by the electronics of the measurement device but also by the electrochemical noise of the electrode-electrolyte interface. The intrinsic electrochemical noise depends on the electrode/electrolyte interface used. Noise of three metals suitable for implantation (Au, Pt and Stainless Steel) are being examined and referenced to Ag/AgCl commonly used as surface biopotential electrode material. Measurements of the electrochemical noise have been conducted in saline, PBS and SBF. Two different sizes of electrodes of every material have been used. Frequency bandwidth of 0.5 – 500 Hz was used in the measurements.
