Scavenging vibration energy from ambient environment has become an important issue when solar energy is not applicable and batteries are not suitable. There are many works on electrostatic vibration energy harvesters, whose power output is influenced by resonant frequency, volume/mass, excitation amplitude, bandwidth, structure configuration, and input/bias voltage. A performance index considering all above factors is proposed in this work. The result shows that this index can compare electrostatic vibration energy harvesters of all structure configurations with different bandwidth and different capacitance.
