There are many energy sources available in the environment but still not well utilized, such as the vibration energy. Therefore, we fabricated and studied a vibration power generator that uses vibrations generated by human walking. The fabricated vibration generator has an inverted pendulum in the center and piezoelectric elements around it. The inverted pendulum operates in the longitudinal and lateral directions. The collision between a weight attached to the tip of an inverted pendulum and piezoelectric elements generate electricity. In this study, we evaluate the power generation characteristics of the fabricated vibrating power generator by means of vibration experiments with different fixed angles. The results show that power is generated uniformly regardless of the fixation angles of the generator.
