Neat stuff. I’m very excited reading about the prospect of internal body (very low power) devices and sensors powered by blood flowing over graphene.
I think a 24/7 glucose monitor is a decade or so away.
As I understand from my Fluid Dynamics class, anything flowing over anything can create electricity. That’s why most gasoline tankers have big chains they drop to form a ground circuit while pumping gasoline.

I think the idea here is that with large sheets of thin metal, it could actually produce a decent amount of electricity for commercial use.
