| dc.description.abstract | the vibration energy harvester is intended to convert ambient environmental energy
into electrical energy. it has great potential to be an alternative to the conventional battery
in low-power electric devices. a traditional vibrating energy harvester consists of a linear
oscillator that operates in a narrow frequency band. nonlinear energy harvesters provide a
promising solution to widen the operating bandwidth. based on the system stability states,
the nonlinear vibration energy harvesters can be classified as mono-stable and multi-stable.
in this study, a tunable multi-stable piezoelectric energy harvester is proposed. the
apparatus can be manually tuned to achieve three states, namely tri-stable, bi-stable, and
mono-stable. it has a compact structure compared to the existing designs. [...] | en_us |
