Welcome to the PF.

This previous thread from here in the EE forum should be of help:

Once you read that thread and do some other reading (assuming wikipedia comes back up tomorrow), let us know if you have specific questions. Remember, this is *your* school project, so you must do the bulk of the research and development work.

These discs can be used as guitar pickups and in that application generate voltages of about 10mV to 100mV... something for you to go on.

But the more no. Of disk produce more voltage that can be sufficiant power to store.
