“…Karimi et al 300 proposed a distributed-parameter model whereby passing vehicles on a bridge were considered as concentrated point mass and distributed mass. Bhaskaran et al 301 numerically analyzed an array of cantilever energy harvesters with different resonant frequencies via the finite element method in order to achieve broadband energy harvesting on bridges.…”

Energy harvesting holds great potential to achieve long-lifespan self-powered operations of wireless sensor networks, wearable devices, and medical implants, and thus has attracted substantial interest from both academia and industry. This paper presents a comprehensive review of piezoelectric energyharvesting techniques developed in the last decade. The piezoelectric effect has been widely adopted to convert mechanical energy to electricity, due to its high energy conversion efficiency, ease of implementation, and miniaturization. From the viewpoint of applications, we are most concerned about whether an energy harvester can generate sufficient power under a variable excitation. Therefore, here we concentrate on methodologies leading to high power output and broad operational bandwidth. Different designs, nonlinear methods, optimization techniques, and harvesting materials are reviewed and discussed in depth. Furthermore, we identify four promising applications: shoes, pacemakers, tire pressure monitoring systems, and bridge and building monitoring. We review new high-performance energy harvesters proposed for each application.

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 paper presents an electromagnetic energy harvester to extract low frequency and low acceleration vibration energy available in a bridge environment. The developed harvester is a multi-mode oscillator with dual electromagnetic transduction mechanisms. The harvester consists of two cantilever beams. The first cantilever beam is split into two equal pieces along its length and the second beam placed in between them coming back to the fixed end and attached at outer end to the first beam. This way instead of a long conventional cantilever beam a compact harvester is fabricated. Two magnets as proof masses are attached to each free end of the beam making it a two degree of freedom system (2-DOF). The magnets are positioned to oscillate inside hand wound coils during operation. An analytical model was developed and COMSOL multiphysics was used to simulate the mode shapes of the harvester. The mathematical model was simulated for open circuit voltage in MATLAB and showed closely matching results with the experimental values. The harvester is characterized in lab for its performance under sinusoidal vibrations at low frequency (3 Hz–15 Hz) and low acceleration (0.01–0.09 g) levels. The 2-DOF harvester has two resonant frequencies of 4.4 Hz and 5.5 Hz and a volume of 333 cm3. It produces maximum voltage of 0.6 V at first resonance on coil-1 and maximum voltage of 1.2 V on coil-2 at second resonance at 0.09 g. At acceleration of 0.09 g the harvester produced 2.51 mW at first resonant frequency and 10.7 mW at second resonance. Moreover, the AC output voltage of the harvester is rectified to DC voltage by a three-stage Cockcroft-Walton multiplier type circuit. The DC power output at 0.05 g was 0.939 mW at first resonance and 0.956 mW at second resonance while maximum voltages of 5.4 V on coil-1 and 4 V on coil-2 were produced.
