1. A method of constructing a piezoelectric device, comprising the steps of:

  • dispensing a first tape onto a moveable track;

    said first tape having a plurality of spaced apart pinholes therethrough engageable with a plurality of spaced apart pins on said moveable track;

    dispensing a first ceramic onto said first tape;

    dispensing a second tape onto said first ceramic;

    said second tape having a plurality of spaced apart pinholes therethrough engageable with a plurality of spaced apart pins on said moveable track;

    securing said first tape to said second tape to form a composite tape;

    increasing a temperature of said composite tape;

    decreasing a temperature of said composite tape;

    and cutting said composite tape to form at least one piezoelectric device.
