How do you convert the charge on the capacitors into
something people can feel? |

You say that like it's a bad thing. |

You'd definitely need something analogous to a brightness control to vary voltages based on skin types. My guess is you'd end up using high voltages (~100V) with no amps. This should give a slight tingle but not anywhere near painful. |

I guess unless you want it to be.... |

This may work, but I doubt it. For one thing, the electrical
conductance of the skin depends hugely on dampness and on
pressure. For another, braille users rely on the light-touch
sensors in the fingertips, which are very densely packed.
This system might stimulate these receptors, but I think it's
more likely to trigger other receptors which are not so
densely packed (eg, heat, pain). |
