1. An apparatus for a piezoelectric generator structure, the apparatus comprising:
the piezoelectric generator structure disposed between an upper platform and a lower platform, wherein the piezoelectric generator structure includes a lower piezoelectric pad, an upper piezoelectric pad, and a connecting shaft;
the lower piezoelectric pad mechanically and electrically coupled to the upper piezoelectric pad via the connecting shaft, wherein the lower piezoelectric pad is configured to compress under a downward motion of the upper platform during a compression movement due to an additional load being applied to an existing load on a top surface of the upper platform, wherein the lower piezoelectric pad produces a first voltage due to the compression movement;
the upper piezoelectric pad configured to compress under an upward motion of the upper platform during a rebound movement of the upper platform, wherein the upper piezoelectric pad produces a second voltage due to the rebound movement; and
the generator structure configured to provide the first voltage and the second voltage to an electrically coupled power storage unit.
