Interesting idea, but where do they plan to have batteries?
Right now normal hearing aids use tiny (but not microscopic) batteries (commonly type 312 zinc-air) that last roughly around a week (if the aids are used 12-16 hours/day).
For something in a dental implant, there will be the need for smaller batteries (and thus would need to be changed more often) that - one way or the other - will need to be inserted in the mouth, with a risk of ingesting them, maybe a "whole" denture, but a dental implant?
