Piezoelectric generator and method of manufacturing the same

A piezoelectric generator comprising at least one unit structure, the at least one unit structure comprising:

• a stainless steel (SUS) substrate having a first area;
• a piezoelectric ceramic plate having a second area smaller than the first area, wherein the piezoelectric ceramic plate is polarized on at least one major surface, and is adhered to the stainless steel (SUS) substrate via an adhesive;
• and
• a flexible printed circuit board (FPCB) connected to a silver electrode formed on the piezoelectric ceramic plate so that the FPCB is electrically connected to the at least one major surface of the piezoelectric ceramic plate,
• wherein an area of the stainless steel (SUS) substrate is larger than an area of the piezoelectric ceramic plate.

A method of manufacturing a piezoelectric generator, the method comprising:

• subjecting a first piezoelectric element comprising a first electrode to polarization;
• attaching the first piezoelectric element to a first substrate;
• and
• attaching a first printed circuit board to the first piezoelectric element.
