Hmmm..

In the peizo electric effect a charge is produced between opposite sides of a crystal by "electron density displacement" in proportion to the stress applied to the crystal. When the stress is removed, the electron density reverts to its previous uniform state and there is no longer a charge. It's hard to see how any kind of permanent field could be created by a succession of minor impacts.
