1. A method of manufacturing a piezoelectric energy harvesting array comprising:

  • forming a plurality of piezoelectric energy harvesting devices;

    connecting masses to one side of the piezoelectric energy harvesting devices and connecting the other side of the piezoelectric energy harvesting devices facing the masses to a base; and

    individually tuning a resonant frequency of each of the piezoelectric energy harvesting devices to prevent mismatch of resonant frequency when the masses vibrate, includingselecting any one of the piezoelectric energy harvesting devices and fixing the rest of the piezoelectric energy harvesting devices to the base, andtuning the selected one piezoelectric energy harvesting device to a reference frequency of the base.
