I get the problem with electro torture in bdsm porn, the obviously fake stuff isn't interesting to me either. However I love the idea of electro torture, if it's done right it can be very interesting to see. There are lots of ways to do it, from cattle prods or tasers to some complicated setups with lots of wiring. Even an electric chair is possible, I have seen something like that at the end of an Arcas story ("Student Body").

For other modern technology, how about a drill? Drilling holes into girls with that should be very painful.

Cigarettes could also be used on some girls, that's another simple yet effective tool, and while not technology certainly modern.
