I'm interested in experimenting with the detection and digitizing of the
voltages involved with human muscle activity. I intend to use the electrodes
they use for EEG testing, placing them over certain facial muscles.
I don't know what sort of voltages I'll see, but I assume they'll be quite
low and I'll need to use a low-noise op amp before I do my A/D conversion.
Anyone out there have a good estimate of the levels I'll see?
