Show more >This article focuses on an intelligent control strategy to improve the performances of shunt-rectifier architectures for vibration energy harvesting. It demonstrates how proper tuning can improve the frequency bandwidth and maximum power of unipolar synchronized electric charge extraction architectures. For resonators with strong enough coupling (k 2 Q. p=2), tuning the duration of charge extraction with the oscillation frequency improves the power harvesting performances. The main differences with other similar solutions such as unipolar synchronized electric charge extraction without tuning strategy or tunable synchronized electric charge extraction are illustrated. In particular, we show how the choice of the shunt rectifier significantly affects the power response of the generator due to electromechanical coupling phenomenon. The analytical study is experimentally validated on a cantilever-based piezoelectric generator.Show less >
