The electric power generation properties of lead zirconate titanate (PZT) ceramic have been studied under various cyclic loading conditions. The maximum voltage increases with an increase in the frequency under the triangular and sinusoidal wave modes, whereas the voltage decreases with an increase in the frequency for the square wave mode. The maximum electric voltage for all wave mode is saturated at around 15Hz, namely, the electric voltage for the three wave modes is almost constant even if the frequency increases by more than 15Hz. The maximum electric voltage increases with an increase in the frequency under the triangular and sinusoidal wave modes, because of the high kinetic energy. For the square wave mode especially at high frequency, a low electric voltage is obtained, which is caused by the switching back of the electric generation arising from rapid loading speed.
