Summary: This paper investigates the performance of four different electromagnetic vibration energy harvesters and determines that the harvester with two opposing magnets performs the best, while the Halbach array with three magnets and one coil configuration provides the highest mass power density. The study also reveals the limitations of using the electromagnetic coupling coefficient as a metric for harvester optimization when the goal is to maximize output power.

Summary: This paper presents a systematic study on the output performance of nonlinear energy harvesters, using theoretical and numerical analysis. The study derives the general analytical expression for output power of systems with different combinations of nonlinear stiffness and damping. It is found that all nonlinear systems have a limit power determined by mass, acceleration, and damping. The results also reveal that asymmetrical damping has no effect on the output performance of symmetrical stiffness systems. Furthermore, the study investigates the influence of nonlinear coefficients on output power with matched load, and reveals a power function relationship between normalized power and matching resistance ratio. These findings provide valuable insights for the design and optimization of energy harvesters.

Summary: This paper analyzes the impact of parametric uncertainties on the dynamics of bistable energy harvesters and investigates how each parameter's variability affects the energy harvesting process. The study uses probability distributions and polynomial chaos to model and propagate uncertainty. Different models of bistable energy harvesters with nonlinear piezoelectric coupling and asymmetries are considered. The findings suggest that increasing the excitation frequency leads to a higher probability of increasing harvested power in the intrawell motion regime, while increasing the excitation amplitude and piezoelectric coupling are more likely to increase power in the chaotic and interwell motion regimes, respectively. The importance of investigating the influence of simultaneous parameter variations is emphasized through an illustrative example.

Summary: With the development of autonomous/smart technologies and the Internet of Things, wireless sensor nodes play a vital role in intelligent mechanical engineering. However, traditional power supply methods face challenges such as layout difficulties and environmental pollution. Therefore, it is crucial to harvest mechanical vibration energy using technologies like the triboelectric nanogenerator to provide in situ power supply for these nodes. This review systematically reviews recent achievements and discusses challenges and development orientation for mechanical vibration energy harvesting based on TENG, which will contribute to the future development of intelligent mechanical engineering in the era of IoT.

Summary: This paper extends the optimization analysis for single-degree-of-freedom vibrational energy harvesters and provides new insights on the optimal load, load power, and power input to output efficiency. The analysis includes the effect of intrinsic resistance and considers both resonant and anti-resonant states. The results reveal the exponential increase in the critical mechanical quality factor and the dependence of optimal load coefficient on the mechanical quality factor and resistive loss coefficient.
