ADJUSTABLE RESONANCE FREQUENCY VIBRATION POWER HARVESTER

摘要

A resonance frequency vibration power harvester (20) comprises an elongate body (36), a first vibration energy harvester device (42) and a weight (46). The elongate body (36) includes a first end (54), a second end (56) and an interior channel (65) extending through at least a portion of the elongate body (36) between the first end (54) and the second end (56). The second end (56) of the elongate body is for connecting to a vibration source (18) such that the first end (54) is cantilevered. The first vibration energy harvester device (42) is attached adjacent the first end (54) of the elongate body, and the weight (46) is joined to the interior channel (65) to adjust a resonant frequency of the elongate body (36).
