Current status of *PROVEN* subdermal induction systems?
edited February 2015 in Coatings, transdermals, other implants
Does anyone have or have references to someone with a functioning subdermal induction/power system, either for battery recharging or for short term power? I've read a lot about things that should work, or things that have been tried but failed. I was wondering what the state is for techniques that actually have been proven to work, or if research isn't at that stage yet?
Wikipedia has a list of the most common ones. https://en.wikipedia.org/wiki/Inductive_coupling
From devices as big as transformers in power stations, towards smaller things like motors, toothbrushes, erotic-toys, down to tiny rfid tags or μm sized structures. Inductive power transfer is working. For mobile-phone charging there are at least 3 concurrent standards for inductive charging that are somewhat popular.
Many cochlear implants are powered via inductive coupling. Pretty much all rechargeable neurostimulation devices come with inductive coupling too. A smaller number of pacemakers also use them.
Even i had a set of coils and capacitors transmitting enough power to run a microcontroller on it over a 2cm airgap. It's really no big deal to make it work. If your demands in power and transmitting distance increase, it's getting more difficult. But within physical limits it's working great.
