Seconded. Keeping in mind that our nerves themselves are operating
based on electricity, I suspect that the basic rule of thumb is:
there's no such thing as safe electrostimulation of sensory nerves.
Your stimulus can either be too weak for anything to be registered at
all, or too strong to be safe.

The margin between these two thresholds on stimulus strength is
probably too small to be safe for everyday usage other than in a
*very* closely controlled environment (say, within shouting distance
of an ICU, with trained medical personnel controlling the apparatus,
given a rather specific medical indication for doing it).
