| 摘要 | Raindrop-driven piezoelectric energy harvesting presents a fundamentally different operating condition from conventional vibration-based systems due to its stochastic and impulsive excitation. While power-management circuits are typically optimized for steady or harmonic vibration, their performance under impact-dominated excitation remains poorly understood. This study experimentally investigates the power-management behavior of a hinged-plate rain energy harvester, focusing on NMOS threshold gating and boost-converter stability. Measurements reveal two distinct electrical regimes: high-amplitude impact-induced voltage spikes (~1.5 V) and lower-amplitude residual vibration outputs (~0.5 V). NMOS gating suppresses low-level leakage under vibration-dominated conditions but provides limited improvement when impulsive impacts dominate. In addition, boost-converter regulation becomes unstable due to the mismatch between transient voltage spikes and vibration-oriented design assumptions. These results indicate that steady-vibration power-management strategies are not universally applicable to rain-driven energy harvesting systems and highlight the need for impact-aware regulation, improved piezoelectric materials, and robust device architectures. |
