摘要

This Note proposed a multi-direction piezoelectric energy harvester with a wide bandwidth and low working frequency, which is distinguished by the multiple working modes of the U-shaped beam and the high capacity of the pendulum in collecting arbitrary vibrations. The structural features are evaluated by finite element simulation and verified by experiments. At least three voltage peaks are generated in the frequency range of 0 Hz-25 Hz, and favorable harvesting consistency in different directions is achieved. The designed structure is adaptable in collecting energy from arbitrary vibration in ambient environments.
