Abstract
We measured the noise and impedance from Pt electrode pairs in a frequency band from 100 Hz to 10 kHz, containing the ENG band (500 Hz 5 kHz). The results show that the Pt electrode noise is the same as the thermal noise from the real part of the electrode impedance, which is a summation of the polarisation resistance and the access resistance. This differs from Ag-AgCl electrodes for which the electrode noise has been reported to be higher than the thermal noise. Our study shows that Pt electrodes are suitable for neural recording.Entities:
