I am testing the impedance of a material that will be used for ECoG electrodes.
I was told to test it at a frequency range from 1 Hz - 100 kHz but why is this range used? I wasnt able to find a satisfactory answer.
Which impedance values are good for recording and why? Is there a range ?
Kind regards

Hi Henry. I would let you posted very soon regarding your first question. For the second question, I suggest you keep the impedence between 0.5- 5 mOhm. at least for my own experiments I choose electrode impedence for EcoG in the range of
