“…[ 230–233 ] As shown in Figure 10F, Li and Jing proposed an X‐structure with the inherent bistable and QZS mechanisms to enhance the wave energy conversion performance significantly. [ 234 ] In Figure 10G, Wang et al. [ 235 ] designed a QZS spring to achieve ultra‐low stiffness in a much larger displacement region, and combined TENG with the QZS mechanism for effectively converting the low‐frequency ambient vibration energy to electrical energy.…”

The Artificial Intelligence of Things (AIoT) connects everything with intelligence, while the increase in energy consumption generated by numerous electronic devices puts forward an impending demand on the power supply. Energy harvesting technology has emerged as a compelling innovation technology for the net zero emissions of the power supply for the AIoT. Although significant advances have been witnessed in energy harvesting, some issues such as poor electrical output, weak environmental adaptability, and low reliability are difficult to satisfactorily resolve. Mechanical intelligent energy harvesting can be defined as the system identifying the external excitation or its own state and reacting to it, rather than relying on electrical sensing elements or a central controller for certain adaptive or programmed functions. The adaptive and programmed functions exhibit great potential in solving the above‐mentioned issues that seriously restrict the development of the energy harvesting technology. Here, a generalized definition of mechanical intelligent energy harvesting is given critically and the design methodology is elaborated. The typical reported energy harvesting systems with the characteristics of mechanical intelligence are reviewed. The key research directions in mechanical intelligent energy harvesting are discussed. The mechanical intelligence is expected to revolutionize the development of the energy‐harvesting technology and pave the way for applications.

“…By adjusting the geometric parameters of the bitable mechanism, this structure can be achieved in different multi-stable states from bistable to four-stable, and the potential barrier can be reduced by increasing the number of steady states. Li and Jing [57] proposed an Xstructured device and applied it to a point-absorber WEC, as shown in Fig. 8.…”

“…For a WEC with a conventional bistable mechanism realized by springs, pneumatic cylinders, or magnets [27,[34][35][36][37][38][40][41][42][43][44][45]48,[50][51][52][53][55][56][57][58][59][60][61][62][63][64] , the overall trend is that the introduction of a bistable mechanism increases the power captured by the WEC if inter-well motion occurs. The maximum power captured by the bistable WEC increases with a decrease in the non-dimensional parameter, and the corresponding frequency is also shifted to a low-frequency region.…”

Wave energy is one of the most abundant renewable clean energy sources, and has been widely studied because of its advantages of continuity and low seasonal variation. However, its low capture efficiency and narrow capture frequency bandwidth are still technical bottlenecks that restrict the commercial application of wave energy converters (WECs). In recent years, using a nonlinear stiffness mechanism (NSM) for passive control has provided a new way to solve these technical bottlenecks. This literature review focuses on the research performed on the use of nonlinear mechanisms in wave energy device utilization, including the conceptual design of a mechanism, hydrodynamic models, dynamic characteristics, response mechanisms, and some examples of experimental verification. Finally, future research directions are discussed and recommended.

With the rapid development of the Internet of Things (IoTs), numerous distributed wide‐area low‐power electronic devices have been utilized in various fields, such as wireless monitoring sensors and wearable electronics. Due to the dispersion and mobility of microelectronic devices, their energy supply faces serious challenges. The inconvenience and non‐environmental friendliness of using traditional centralized low entropy energy and chemical batteries to power distributed microelectronic devices are becoming increasingly prominent. Environmental energy harvesting technology with high entropy characteristics is considered an effective solution for low‐power electronic devices. This paper comprehensively reviews the recent progress in microelectronic technologies based on energy harvesting and signal sensing. First, state‐of‐the‐art micro‐power electronic devices in humans, animals, and the environment are introduced. Secondly, the available micro‐energy sources in the environmentare elaborated and summarized. Then, the principles and characteristics of ambient microenergy harvesting technologies based on different mechanisms are classified, summarized, and analyzed. In addition, this work comprehensively summarizes the applications of self‐powered micro‐electronics technology in 11 different fields, including human, animal, and environment. Finally, research challenges, technical difficulties, and research gaps in self‐powered microelectronics based on micro‐energy harvesting technology are discussed and summarized.
