Flexible Piezo Transducers
Hello everyone, I am currently the new kid on the block.
I don't have much time for a proper introduction (I've got more than enough essays to write at this moment)
but this topic has been on my mind for the past couple of days, so i was hoping i could have it debunked or better yet improved.
So I ran into a article on harvesting electricity from a beating heart with a piezo transducer to power a pacemaker.
This got me wondering if it would be possible to implant small strips of piezo transducers along the back side of my fingers (or something similar) and have them connected to a charging module somewhere in the wrist, and use it to enable other implants to be self-sustainable.
I haven't done too much research on piezoelectricity but I'm curious if something like this would work.

Main limitation is set by physics where energy equals force * distance. Your distances will typically be within less than 1mm, the forces probably not above 0.2N, gives you about 0.0002J per actuation cycle at max. If you are a really fast hand-waver you may get that 5 times per second. Chances are you won't get much more than 1mW. Even the most simple inductive charging from just an LC combination will easily get you 10 to 50 times the output power (without waving your arm like crazy).
Thanks for the input
This is what I had in mind:

But I suspect that this doesn't change the output situation.
When I have some more free time I'll do more research.
How "easy" would something like this be to replicate? and how expensive?
Long story short: thermoelectric generators work only on the skin, not inside. And even on the skin, they require rather chill temperatures to produce noticeable output power
