You mean they're powered by electromagnetic radiation?!?!!?

ATP? Fat?

RTFA

High frequency waves? HA!... You'd be better off with low frequency induction and a subcutaneous coil. Use that to charge a super capacitor and you're good for hours or days.

Not exactly new. One of the challenges of inductive power transmission in the realm of implants is to make them MRI safe (MRI safe pacemakers were introduced in 2011), which is completely doable. There is a guy at my university who drew up plans for an inductive CSF shunt. The idea was that you could put the charging coil on someone head and the smart shunt would receive the power/tell you the ICP, so you could instantly know whether it was working or not. A pretty smart/cheap idea.

I've always wondered if you could stick a fuel cell in someone's colon and power stuff off the methane generated. How many watts per day do you think someone flatulates?

Not quite the same, but they do have cells that can oxidize glucose/produce power. So they'd just run on blood sugar. They don't generate much power, but probably someday you could have an implantable "chip" that is able to monitor blood sugars.

Bravo! Great reference!

don't ask where they plug them in

Methane can be a pretty powerful fuel.
