Abstract
A broadband piezoelectric rotational energy harvester with upward and downward cantilevers was de-veloped. The system captures energy from both directions of rotation using PVDF materials. It was tested under two aerospace vibration profiles with distinct frequency content. The downward cantilever produced a peak average power of 57.8 µW. The upward cantilever reached 33.5 µW under different excitation. Results confirm broadband rotational energy harvesting capability for aerospace vibration environments.
