| 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 |
