Provided is an apparatus for generating direct current using continuous polarization change of piezoelectric materials. For example, a piezoelectric direct current generator includes a first electrode, a polarized piezoelectric material layer disposed on a first surface of the first electrode, and a second electrode disposed on a surface opposite to the first electrode and coupled to move along the piezoelectric material layer while pressing the piezoelectric material layer.
