Love the project and concept. Signed up to your email list. My first company was a DARPA R&D contracting firm and at one point we made our own EEG's. We solved some interesting problems but being in a helmet in a war is probably an easier use case than a head band that's comfortable to sleep in... What are you using for electrodes in your prototypes? Do you use an aerogel or the usual synapse paste? I can't imagine a consumer product would work for the later but maybe the former. The state of the art for my old applications seems to now be micro/nano scale electrodes, from only a quick google. I've been out of the space for a bit shy of a decade so I'm interested to know how far it's come and how you're going to make the product comfortable. |

We are not using any gel or water. It took us over 6 months of experimenting and re-implementing different papers, before we came across our current design. Which was the result of a fortuitous accident.
If you look at the Muse S headband reviews on Amazon, https://www.amazon.com/MUSE-Headband-Overnight-Meditation-Re..., you'll see many people having difficulty with electrodes tearing. I tried a Muse S myself, and quickly saw wear on their electrodes.
The design we're currently using, I've had for over 1 month with no degradation in signal quality - I live next to the ocean, so lots of salt in the air, and I try to treat the electrodes badly. The other bands that we have in use are also maintaining good signal over the few weeks of use.
The formula we're working on with industrial design atm is the balance of comfort, signal quality (maintain connection - as I said, electrodes are now good), and robustness.
