This study is based on energy harvesting from vibration and deals with the comparison of different techniques. In the present scenario, energy harvesting has drawn the attention of researchers due to a rapid increase in the use of wireless and small-scale devices. So, there is a huge thirst among scientists to develop permanent portable power sources. In the surroundings, a lot of unutilized energy is wasted which can be collected and used for power generation. Research works have been extensively carried out to develop energy harvesting devices catering to the increasing needs of being efficient and economical. Effective energy harvesting mainly depends on the design of the transducer. Different types of design techniques, material properties, and availability of energy harvesters are reviewed in this paper. The paper aims to explore the advantages and limitations of different energy harvesting principles, advances, and findings of the recent past. This study also discusses some of the key ideas for the enhancement of power output. This paper provides a broad view of the energy harvesting system to the learners, which will facilitate them to design more efficient energy harvesting devices by using different principles.

“…The genetic algorithm (GA) is an effective solution for optimizing the dual-stage BEH, since it is one of the intelligent algorithms that do not require the explicit information of the performance index. The GA has been successfully applied for optimal design of many oscillation systems for vibration energy harvesting [32][33][34][35] and vibration control [36][37][38]. Raj and Santhosh [32] investigated optimization of a mono-stable nonlinear system comprising vibration absorber and vibration energy harvester based on the GA in combination with response surface methodology.…”

This study investigates robust optimization of a dual-stage bistable energy harvester (BEH) considering parametric uncertainties, so as to efficiently search the robust optimal design parameters for enhancing vibration energy harvesting performance in a working bandwidth. Dynamic model of the dual-stage BEH and numerical method of predicting the broadband power transmissibility are presented, the fidelity of which is verified by the analytical solutions and experimental results. Then, the optimization problem is defined, where the performance index for optimization is calculated based on the power transmissibility in a working bandwidth. To ensure the robustness of optimization results, instead of straightforward maximizing the performance index, the genetic algorithm is used to maximize the mean value of the performance indices corresponding to the parametric uncertainties which satisfy normal distribution. Results show that compared to the optimization disregarding the uncertainties, the proposed robust optimization method can significantly enhance the overall performance and robustness of the dual-stage BEH subjected to the parametric uncertainties. Therefore, the comparative results validate the effectiveness of the proposed method for robust optimization of the dual-stage BEH.

“…Several studies are focused on the vibration sources and transmission paths of pumped storage power stations in the context of water conservation and the hydropower industry [4][5][6][7] . Regional environmental vibrations and noise in the diversion pipeline of pumped storage power stations are new problems, with a paucity of research, technical know-how, design specifications, and regional vibration control standards [8][9][10][11] available to address them.…”

High‐frequency pressure pulsations are hydraulic phenomena that are frequently observed in pumped storage power stations. These pulsations can propagate through the steel pipes, concrete lining, and the surrounding rock system, which in turn may have detrimental effects on the environment, such as noise pollution, and relocation of the local residents. This paper proposes a vibration‐damping concept that involves wrapping a local soft cushion layer outside the buried steel pipe; this layer could partially eliminate the pressure fluctuations in the headrace tunnel, thereby reducing the ground vibrations caused by the pressure pulsations. In this study, the finite element method was used to model the propagation of vibrations in the surrounding rock and fluid‐filled pipes, including static simulation of the structure, and dynamic simulation of the surrounding rock. The simulation results suggest that adding an appropriate local soft bedding layer can effectively reduce the ground vibrations by more than 60% and the possible surface noise within the standard vertical vibration norms. The inhibitory effect of the soft cushion on the propagation of vibrations is determined by the wrapping angle, thickness, and material of the bedding layer. This effect increases with increasing wrapping angle and thickness of the bedding layer, and decreases with increasing elastic modulus of the material. After the addition of the bedding layer between the steel pipe and concrete lining, the pressure in the inner pipe is primarily borne by the steel lining rather than the coupling of the steel lining, concrete lining, and the surrounding rock. Hence, the thickness of the part of the steel liner in contact with the soft bedding layer should be increased. In addition, the thickness variations in the steel pipe joints should be smooth to avoid stress concentration.
