Magnetic measurements are both physically possible and don't have muscle interference. For example https://arxiv.org/abs/2001.03534 https://arxiv.org/abs/2001.0

Magnetic measurements are both physically possible and don't have muscle interference. For example https://arxiv.org/abs/2001.03534 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.
