Hello, I want to build a piezoelectric energy harvester, that can store the energy whenever it it pushed, into a standard 3,2v Li-on battery.
This is a project where I want to build a powerbank, that charges itself in the shoe, through pressure onto a Piezoelectric element.
My problem right now, is that I want to temporarily store the voltage into a Supercapacitor, so I can slowly charge it up to 3,6v, and afterwards make it automatically discarge into the 3,2v battery, until the supercapacitor reaches 3,2v and stops until it reaches 3,6v again from the piezoelectric element.
This process should be autonomous, but due to my lack of knowledge in the field, I'd like to know if anyone here would be willing to help me out with making this project a realization!
I've attached a simple diagram of what I currently think, the system should look like.
