“…So, providing a sustainable power source for these devices is the main problem being faced. Vibration energy harvesters have been extensively studied for their potential to provide a permanent power source for the operation of these devices [4][5][6][7][8][9][10][11]. In particular, galloping energy harvesting technology has become a hot research topic in the field of flow-induced vibration energy harvesting due to the advantages of gathering high energy density during energy harvesting applications [12][13][14][15][16][17].…”

In this paper, the response properties of galloping energy harvesters under bounded random parameter excitation are studied theoretically. The first-order approximate solution of the galloping energy harvester is derived by applying the multi-scales method. The expression for the largest Lyapunov exponent that determines the trivial solution is derived, and the corresponding simulation diagrams, including the largest Lyapunov exponent diagrams and time domain diagrams, verify our results. Then the steady-state response moments of the nontrivial solution are studied using the moment method, and the analytical expressions for the first-order and second-order moments of the voltage amplitude are obtained, respectively. The corresponding results show that wind speed enhances the steady-state response moments of the voltage amplitude. Meanwhile, the voltage output can be controlled by adjusting the cubic coefficient. To further verify the response characteristics of the galloping energy harvester, the stationary probability density functions of the displacement and velocity are obtained by the Monte-Carlo simulation method. The results show that the wind speed enhances the displacement of the bluff and the damping ratios should be reduced as much as possible to improve the performance. What's more, the piezoelectric materials also impact the performance of the energy harvester.

Harvesting cable vibration energy via electromagnetic dampers has been demonstrated as potential power supplies for wireless sensor networks or semiactive control devices. However, how the inerter enhances the energy harvesting performance of the electromagnetic damper when applied to a bridge stay cable remains largely unknown. This paper presents a full-scale experimental study on harvesting the vibration energy of a 135 m-long cable using an electromagnetic inertial mass damper (EIMD). The EIMD integrates an electromagnetic damper and an inerter. A numerical model of the cable-EIMD system was also established using Matlab/Simulink for performance analysis. In the free vibration test, the EIMD could achieve the peak output power of 61.52 W and average output power of 13.80 W, when the inerter and the load resistance are optimized, considering an initial displacement of 100 mm near the mid-span of the cable. The corresponding energy harvesting efficiency was up to 25.31%. However, the energy harvesting performance of the EIMD degrades under ultra-small-amplitude vibration conditions due to the overlarge parasitic damping induced by Coulomb friction. Besides, experimental data uncover a 53.08% increase of average output power due to the inerter used, while numerical results indicate a tremendous increase of output power up to 126.1% because of assuming low parasitic damping. The EIMD with the optimal parameters (inertance, damping coefficient, and load resistance) can provide superior energy harvesting performance owing to the energy amplification mechanism induced by the inerter.

“…In recent years, piezoceramics transducers have been used to monitor structural health [28][29][30]. Piezoceramic transducers have their superiorities of wide frequency range [31][32][33], low cost [34,35], energy harvesting [36][37][38], and the dual functions as a sensor and an actuator. Among various piezoceramic materials, lead zirconate titanate (PZT) has the strongest piezoelectric effect and can be fabricated in different shapes [39,40].…”

To understand the characteristics of longitudinal grouting quality, this paper developed a stress wave-based active sensing method using piezoceramic transducers to detect longitudinal grouting quality of the prestressed curved tendon ducts. There were four lead zirconate titanate (PZT) transducers installed in the same longitudinal plane. One of them, mounted on the bottom of the curved tendon duct, was called as an actuator for generating stress waves. The other three, pasted on the top of the curved tendon duct, were called as sensors for detecting the wave responses. The experimental process was divided into five states during the grouting, which included 0%, 50%, 75%, 90%, and 100% grouting. The voltage signals, power spectral density (PSD) energy and wavelet packet energy were adopted in this research. Experimental results showed that all the amplitudes of the above analysis indicators were small before the grouting reached 90%. Only when the grouting degree reached the 100% grouting, these parameters increased significantly. The results of different longitudinal PZT sensors were mainly determined by the distance from the generator, the position of grouting holes, and the fluidity of grouting materials. These results showed the longitudinal grouting quality can be effectively evaluated by analyzing the difference between the signals received by the PZT transducers in the curved tendon duct. The devised method has certain application value in detecting the longitudinal grouting quality of prestressed curved tendon duct.
