    Please use a transformer to isolate yourself from the mains. Be sure there are no components crossing over the isolation barrier. And check your grounds.

    If you are connecting electrodes to people I would recommend that you use battery power, no connection to the power lines at all.

    It would be interesting to see your complete design. As we need this to draw any conclusion.
