electrode shapes, sizes, saline usage
I've been looking into designing an EEG Headset using the OpenBCI Ganglion board. However, the concept designs that I've been working with would be greatly improved if the dry AgCl electrodes were different shapes and sizes, or if they used a different medium.
I was wondering if other anybody else have considered or tried making your own dry comb electrodes, and is it feasible for me to use home-made electrodes for a trial? What are the main considerations when I should go about producing and designing the electrodes?
We've also been considering using saline electrodes as well. I've read that the ganglion device is compatible with the OpenBCI saline cap, is it possible for us to use custom saline electrodes?
