Hello,

I purchased Energy Harvester Breakout - LTC3588 to measure harnessed energy from buzzer. Could I ask how can I connect them to harvest maximum power and voltage in series or parallel? I think one breakout is enough for two piezo-bender. And is this break out is enough for seeing amount of voltage or power? I mean do I need to inductor or capacitor?
I would be thankful if you give one schematic plan of what I need to do.

Best

Actually, I have a problem in connections. My point of view is just to connect piezo-benders to PZ1 and PZ2. and then no knowledge about what should I do.
My case is not so complicated. I just want to harvest energy from piezo-benders and store it in battery. My point of view is that this (Energy Harvester Breakout - LTC3588) could rectifies AC to DC and I need just one capacitor(battery) ti store it. Could I send you what exactly I need? If yes, how can do it?

Do you have any idea, the smallest foggiest of tiniest of ideas of exactly how much "energy" you'll actually "harvest" from 2 "piezo-benders"?
On a good day?
With perfect components?
With all the planets in alignment?
Any idea at all?

Why not just do the experiment? Connect one piezo according to the documentation, and see how it works. Try other combinations.

I know that is too small. But this is a test, for this reason it does'n t matter. Just want to do it.

I have limited amount of them. So, I want to make sure to how need to do, then continue.Actually, I am not electricall engineer and nobody help to me.
