Can I use the piezo-electric crystal to charge a small battery and connect the battery to a load.
The problem here is that the battery has to supply current to the load for a short period. Then it has to be recharged by the crystal. will I be able to use the same battery for charging and discharging?

The circuit for piezo-electric storage found in the internet is

Should I directly connect the load to the battery.

Can I be able to feed back the vibration produced by the load to PZT and hence using it for charging the battery

Here is one way to do it:

And another:

And some advice on how to build your own:

Note that the piezo is a high-voltage, low current device.
