摘要： A vibration energy harvester, a power accumulator and a power supplier, including: a multi-stable shell with one or more bistable regions and at least one piezoelectric element fixed on a surface of the multi-stable shell. Each of the bistable regions has two different stable configurations, and different combinations of the stable configurations of the one or more bistable regions make the multi-stable shell have a plurality of different stable configurations. The one or more bistable regions are switched between the two stable configurations thereof when being excited by vibration energy, so that the multi-stable shell is switched between the plurality of stable configurations to deform the piezoelectric element to generate electric energy.
