Magnetic measurements are both physically possible and don't have muscle interference. For example https://arxiv.org/abs/2001.03534 is a magnetic field sensor that measures brain activity and runs off a USB port. It's probably a couple decades away, but at least it's feasible.

Here's a USB-powered unshielded MEG sensor that you can just carry out into the woods https://arxiv.org/abs/2001.03534 So that's new.

Preprint: https://arxiv.org/abs/2001.03534 The papers describe a new magnetic field sensor that can measure Brain signals. What's new is that you can do it without a million dollar shielded room. It's just powered by USB-C on a MacBook.
