I'm curious about a topic concerning implants, either medical or cosmetic. Would such questions be on topic here?
This is not for a specific treatment but for my self-education.
The question is like this (I'd formulate it more detailed when asked on the main site).
Currently when you have to power an implant (like a pace-maker) you either have a battery (which need changing) or have an constant open wound where the power plugs are. Why can't one implant a magnetic generator to recharge a battery by applying a rotating magnetic field?
