|Abstract:||This work proposed a hybrid frequency broadening (HFB) mechanism in micro-scale for vibration energy harvesting with ultra-wide bandwidth. A strong HFB behavior is induced by the Duffing stiffening of the clamped-clamped beam stretching and further stimulated continuously by three distributed resonances including out-of-plane mode I at 62.9Hz, torsion mode II at 82.1Hz, and twist mode III at 150Hz. At the acceleration of 1.0g, the microfabricated device with a small area of 6×6mm2 is able to broaden the operating bandwidth from 62.9Hz to be as wide as 383.7Hz. This design methodology can be implemented for efficient electromagnetic energy harvesting. © 2014 AIP Publishing LLC.|
