“…The devices were tested at an acceleration level from 0.075 g to 0.6 g and the resonant frequency of these BEHs ranged from 4 to 27 Hz. The load resistance mostly varied in the available literature below 100 Ω but a maximum load resistance of 335 Ω (Gaglione et al, 2018) was also used. The power density for most harvesters is reasonable but the harvester reported by (Hou et al, 2018) has a power density as high as 176.5 µW/cm 3 , which is because of the larger size of the harvester…”

“…One of the reasons for this difference is that the harvesters are tested in-lab at higher acceleration levels and at resonant frequencies under sinusoidal vibrations which are usually not available at the bridge site. For example, the in-lab output power for BEH (Gaglione et al, 2018) was 78.9 mW which was the highest, however, its output average power on the bridge site was only 1 mW. On the bridge site, most of the harvesters were tested for a few min or hrs., however, few harvesters were analyzed (McCullagh et al, 2014; Peigney and Siegert, 2013) for months.…”

“…The resonant frequency of these BEHs ranged from 3.1 to 23.5 Hz. The excitation acceleration ranged from 0.0036 g to 0.06 g except for two bridges (Galchev et al, 2011; Gaglione et al, 2018). The power output of the BEHs on the bridge site was in the μW range except for one harvester (Sazonov et al, 2009) having a power output of 12.5 mW.…”

“…Tamar Bridge in southwest England was used to record vibration data for 2 days in real traffic conditions (Gaglione et al, 2018) using a direct and autoparametric vibration energy harvester. The selected bridge was a suspension bridge having a total length of 563 m with a main span of 335 m. The acquired data was used in the lab to estimate the power output and multi-hop data transmission protocol to be able to use the harvester in a real bridge environment.…”

Vibration energy has the advantage of abundant availability in the environment of the bridge structure due to consistent traffic flow and high-speed wind blowing. The vibration energy present at the bridge site can be harvested for powering the wireless sensors mounted on the bridge for health monitoring and making the system self-powered. The bridge vibrations are usually low frequency and low acceleration excitations, therefore, its transduction to useful electrical energy is a challenge. However, several techniques are being utilized to harvest the bridge vibration and a variety of bridge energy harvesters are being developed for this purpose. This work has reviewed energy harvesters claimed to be designed for bridge vibrations. The study is split into two categories, first section discusses the energy harvesters developed for bridge vibrations tested only in-lab environments. The second section is about the harvesters that have been characterized on real bridge structures to verify their effectiveness. The study reveals that the bridge energy harvesters can extract enough power to operate the wireless sensors for the health monitoring of bridge structures. Moreover, the architecture, fabrication, input excitation, and output performance of the reported harvesters with modeling techniques are discussed.

This study proposes an optimization strategy for bridge applications with a vibration-based energy harvester design. Piezoelectric cantilevers with multiple degrees of freedom (DOF) are designed and optimized to match resonant frequencies with the vibration frequencies of a full-scale bridge structure under different loading conditions and measurement locations. The specific optimization procedures include bridge vibration acceleration measurement, simulation model development for estimating the resonant frequencies, a regression model for optimization of mass combinations, and final installation on the full-scale bridge for validation. The results show that the simulation model predicted the resonant frequencies of cantilevers with less than 1 Hz difference compared with laboratory measurements. Following the entire optimization procedures proposed in this study, the optimized 2-DOF and 3-DOF cantilevers were capable of generating 18.9 [Formula: see text] J and 23.4 [Formula: see text] J energy under one loading pass, respectively, which were significantly higher than those from the baseline designs. The feasibility of the proposed optimization strategy was demonstrated and validated for vibration-based energy harvesting from bridge structures.
