Abstract
A resonance frequency vibration power harvester includes an elongate body, a first vibration energy harvester device and a weight. The elongate body includes a first end, a second end and an interior channel extending through at least a portion of the elongate body between the first end and the second end. The second end of the elongate body is for connecting to a vibration source such that the first end is cantilevered. The first vibration energy harvester device is attached adjacent the first end of the elongate body, and the weight is joined to the interior channel to adjust a resonant frequency of the elongate body.
