“…Wristband energy harvesters are mostly driven by magnetic beads, which effectively convert inertial kinetic energy into electrical energy. As shown in Figure 8g, Shi et al [354] proposed a wristband piezoelectric-electromagnetic hybrid energy harvester driven by magnetic beads to harvest energy from arm swings. The movement of the human body drives the rolling of the magnetic beads, and the magnetic beads pass through the coil and drive the piezoelectric beam to vibrate, realizing the conversion of kinetic energy into electrical energy.…”

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.

Wireless sensor networks that enable advanced Internet of Things (IoT) applications have experienced significant development. However, low-power electronics are limited by battery lifetime. Energy harvesting presents a solution for self-powered technologies. Vibration-based energy harvesting technology is one of the effective approaches to convert ambient mechanical energy into electrical energy. Various dynamic oscillating systems have been proposed to investigate the effectiveness of energizing low-power electronic sensor devices for supporting various IoT applications across engineering disciplines. Phononic crystal structures have been implemented in vibrational energy harvesters due to their unique bandgap and wave propagation properties. This work proposes a Rubik’s cube-inspired defective-state locally resonant three-dimensional (3D) phononic crystal with a 5×5×5 perfect supercell that contains 3D piezoelectric energy harvesting units. The advantage of defect-induced energy localization is utilized to harness vibrational energy. The 3D piezoelectric energy harvesting units are constructed by the buckling-driven assembling principle. Adapting to the low-frequency and broadband characteristics of ambient vibration sources, soft silicone gel is used to encapsulate the buckled 3D piezoelectric units, which are embedded in the 3D cubic phononic crystal to assemble an entire system. The energy harvesting performance of various defective layouts and their defect modes is discussed. The results demonstrate that the harvester functions well under multidirectional, multimodal, and low-frequency conditions. The proposed methodology also offers a new perspective on vibrational energy harvesters for defective phononic crystals with superior working performance.

“…In recent years, the relentless progress and evolution of Internet of Things have led to the widespread proliferation of low-power wireless sensor networks used for perceiving and collecting signals such as sound, light, force, and heat [1][2][3][4]. Conventional battery-powered solutions suffer from limitations in energy storage capacity, often necessitating frequent replacement or recharging, making it challenging to meet the power supply needs of microelectronic devices, especially in specialized working environments such as deep-sea locations, deserts, nuclear reactors, and volcanic craters [5][6][7]. Energy harvesters are designed to address these limitations by collecting renewable energy sources such as thermal energy, rain energy, wind energy, solar energy, and vibration energy from the environment and converting them into electrical energy to power sensors or electronic devices, which not only fulfill the power supply needs of microelectronic devices in certain specialized environments but also offer environmental sustainability and pollutionfree energy generation [8][9][10].…”

The magnetically induced multi-stable piezoelectric vibration energy harvesters have garnered significant attention due to their strong nonlinear characteristics, wide operating bandwidths, and high electromechanical energy conversion efficiency. However, a traditional penta-stable design typically requires four rectangular external magnets. The excessive number of structural parameters amplify complexities in system optimization, dynamic analysis, and prototype installation, impeding harvester manufacturing and application. This study presents a novel penta-stable harvester design that utilizes interaction forces among a rectangular magnet and two annular magnets, resulting in a simplified system requiring only two external magnets. This design approach streamlines system design, dynamic analysis, and prototype installation, providing a fresh perspective on magnetic penta-stable vibration energy harvester design. The magnetizing current method is employed to accurately determine the system's magnetic field and magnetic force. Stability analysis indicates that the multi-stability of the harvester is influenced by both the vertical magnetic force and equivalent linear elastic force, which can be effectively controlled by adjusting the system's components. Dynamic simulations conducted under Gaussian white noise excitation confirm the penta-stable behavior of the system, and the dynamic responses verify that a shallower potential well depth contributes to the system's ability to attain a higher output voltage. Experimental validations closely align with simulation results, providing strong evidence for the accuracy of the study's findings. Furthermore, a practical application experiment demonstrates the harvester's capability to power a hygrothermograph, highlighting its potential for real-world energy harvesting applications.
