Abstract: A piezoelectric generator using moving-load and a generator system including the same are provided to enable its size to be freely adjusted according to situations, thereby broadening applicability. An upper plate(100) is installed the same height as a ground surface(160). A fixing box(150) supports an edge portion of a top plate according to the shapes of the top plate. A damping spring(105) is positioned between the edge portion and the fixing box. A pressure pin(110) is connected to the lower part of the top plate and delivers the pressure applied through the top plate. A piezoelectric(120) generates the power from the pressure delivered through the pressure pins. A metal plate(130) is located in the lower part of the piezoelectric and helps the piezoelectric to be restored.
