Application of piezo-electric effect

  1. Apr 7, 2014 #1
    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 http://ej.iop.org/images/0957-0233/23/1/015101/Full/mst399991fig10.jpg

    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
