Piezoelectric transducers convert mechanical strain from bridge vibrations, wind loading, or pedestrian footfall into usable electrical energy—enabling maintenance-free sensor networks.
Modern harvesters use lead zirconate titanate (PZT) composites engineered for broadband resonance, capturing energy across 1–500 Hz—covering most civil infrastructure vibration spectra.
