I'm in the middle of my thesis that cuts me between failure and graduation.
I would like to ask if what i'm doing is right. I'm aiming to harvest energy in order to store them into a rechargeable battery.
I'm simply following what the Datasheet tells me (and the Schematic too).
In terms of the setup

even though D0 & D1 is left untouched, Multimeter doesn't show Vcc = 3.3V
Is it because I used the wrong piezoelectric material as a source? (I don't have any options with it)

I have read other forum posts about Vcc testing and yes I used the 9V battery to Vin-GND to test it out and we have the same outcome.
Note: The LTC3588 fell once because of mishandling by my teammate, at typical table height distance. No damage or cracks whatsoever.

Why does the schematic show Vcc and GND connected together by a wire?

Now that you've mentioned it...
Now I removed the shorted Vcc https://imgur.com/a/CnXvj
It only reached 3.5V in 200mV multimeter setting (probably around 0.35V)
still didn't generate a 3.3V like what the datasheet told me (that setting was in 200mV, meaning it didn't even reach it)
and removing the 10uF (25V) Capacitor gives me 1.6V in 200mV multimeter setting
