“…Highway bridge is an effective way for pedestrians and cars to cross physical barriers, and bridge safety is also crucial to driving safety. Cao et al [470] proposed a piezoelectric-electromagnetic hybrid wind energy harvesting system for wind energy harvesting on canyon bridges to power low-power sensors for bridge health monitoring. In addition to harvesting wind and solar energy, the kinetic energy generated by vehicles is an excellent renewable energy source.…”

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.

Wind energy as a renewable energy source is easily available and widely distributed in cities. However, current wind-energy harvesters are inadequate at capturing energy from low-speed winds in urban areas, thereby limiting their application in distributed self-powered sensor networks. A triboelectric–electromagnetic hybrid harvester with a low startup wind speed (LSWS-TEH) is proposed that also provides output power within a wide range of wind speeds. An engineering-implementable propeller design method is developed to reduce the startup wind speed of the harvester. A mechanical analysis of the aerodynamics of the rotating propeller is performed, and optimal propeller parameter settings are found that greatly improved its aerodynamic torque. By combining the high-voltage output of the triboelectric nanogenerator under low-speed winds with the high-power output of the electromagnetic generator under high-speed winds, the harvester can maintain direct current output over a wide wind-speed range after rectification. Experiments show that the harvester activates at wind speeds as low as 1.2 m/s, powers a sensor with multiple integrated components in 1.7 m/s wind speeds, and drives a Bluetooth temperature and humidity sensor in 2.7 m/s wind speeds. The proposed small, effective, inexpensive hybrid energy harvester provides a promising way for self-powered requirements in smart city settings.

For the purpose of improving the operating bandwidth and output power of piezoelectric vibration energy harvesters (PVEHs) in low‐frequency environment, a novel energy harvesting collaborative strategy based on the synergy of multi‐frequency technique and magnetic nonlinear technique is proposed. In order to reveal the working mechanism of the proposed strategy and determine the influence law of the key parameters on the output performances of system, theoretical modelling, simulation analysis and experiments have been carried out. This study proved the feasibility of the two techniques cooperating and complementing each other on the mechanism level, and optimized the ability of the inner and outer beams to capture energy under the action of the pair of magnets on the structural level. After the optimization of key parameters, the output performance of the proposed PVEH utilizing multi‐frequency and magnetic structure is higher than the counterpart only based on multi‐frequency cantilever structure. In an optimal configuration, the fabricated prototype can finally obtain a maximum power of 2.68 mW and a bandwidth of 1.39 Hz under 0.2g acceleration with 0.03 MΩ load resistance. The proposed piezoelectric energy harvesting collaborative strategy can improve the output performance of piezoelectric vibration energy in practical vibration application environments.This article is protected by copyright.
