Hello everyone.
I've got this piezo sensor
From the website and this pdf we can read that it will generate up to 70V.
I've set up simple circuit("Quick Start Circuit" from the pdf - sensor with 5.1V zener acros) and connect it to multimeter, I start tapping, bending and applying all kinds of stress on this little device, but max voltage it created was 0.6V.
What am I missing here?
TIA
