Abstract	This paper demonstrates the harvesting of low-frequency and low-amplitude vibration energy from a suspension bridge. The performance of a Parametric Frequency Increased Generator (PFIG) [1] is evaluated at different locations along the bridge. Bridge vibrations have very low acceleration 0.1–1 $m/s^{2}$ and variable frequency characteristics (1–40 Hz), making them very challenging to harvest. Field test results show consistent operation along the length of the bridge, producing 0.46–0.72 µW of continuous (average) power (peaks in the range of 30–100 µW), independent of the location of the harvester on the bridge, and without any modifications or tuning. These results pave the way for installing a network of wireless structural health monitoring sensors throughout the bridge without regard to the specific characteristics of the vibration at each location. The fabricated device has a volume of 43 $cm^{3}$ (68 $cm^{3}$ including casing).
