Good use of tech. Hardest thing will be corrosion on the fabric electrodes. Muse S has much to teach if you haven't looked at them yet.

We don't use fabric electrodes, we've developed our own conductive silicone. The other thing to learn from Muse S is that mastoid (over ear) electrodes are nearly impossible. We have comb electrodes similar to dreem.

Though, I don't think corrosion is the issue with Muse S, the electrodes tear as I understand it. Either way, they are not robust enough.
