A Novel Ropes-Driven Wideband Piezoelectric Vibration Energy Harvester
This paper presents a novel piezoelectric vibration energy harvester (PVEH) in which a high-frequency generating beam (HFGB) is driven by an array of low-frequency driving beams (LFDBs) using ropes. Two mechanisms based on frequency upconversion and multimodal harvesting work together to broaden the frequency bandwidth of the proposed vibration energy harvester (VEH). The experimental results s...
متن کاملWideband Piezoelectric Energy Harvester Tuned Through its Electronic Interface Circuit
This paper reports a novel technique enabling to tune the resonant frequency of linear inertial piezoelectric energy harvesters through the control strategy of the associated electronic interface circuit. When associated with piezoelectric devices exhibiting high electromechanical coupling, it is expected to enable the variation of the resonant frequency in large proportions.
