Piezoelectric sensors - Energy harvasting
Marco:
You should probably prestress the piezo discs, they are meant to bend like this along the entire edge of the disc, not compress or bend along just one axis.
So put a tiny bit of rubber in between two discs and then clamp/glue the edges together. That way when you compress the rubber they bend like they are supposed to.

Might be aware of this, might not, i found it very interesting read though.

Thank you, I am going to conduct some experiments and will come back with a feedback!!
