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.

Triboelectric nanogenerators (TENGs), as a novel energy harvesting technology, have attracted increasing attention. This review paper focuses on the application of TENGs in flow energy harvesting and self‐powered flow sensing systems, as well as the latest research progress in this field. First, the working principle of TENG is introduced in detail, including the electrification mechanism and four basic working modes. Subsequently, the common applications of TENG‐based flow energy harvesting are systematically classified and summarized. In addition, the designs and principles for harnessing wind energy, wave energy, water flow energy, and droplet energy are illustrated individually. Furthermore, the common applications of TENG in flow sensing are elucidated, involving flow velocity and direction, flow rate measurement, respiration monitoring, water level, and wave motion monitoring. Finally, the current challenges in this field, such as the stability of TENG performance, scalability and integration, environmental impact and durability, etc., are discussed and future research directions, such as developing new TENG materials and designing more high‐efficiency TENG structure, are proposed. It is hoped that this review paper can actively promote the research and application of TENGs and contribute to the development of this field.

Mechanical equipment is ubiquitous in industrial production, and the vibration energy generated by its operation usually cannot be effectively harvested, resulting in huge energy waste. Meanwhile, real‐time monitoring of machine operation can be achieved by collecting vibration information. Indeed, vibration energy harvesting and vibration monitoring are of great significance for the development of green energy and machine fault diagnosis. As an emerging power generation technology, triboelectric nanogenerator (TENG) has shown extraordinary potential in the field of vibration energy harvesting and vibration monitoring. First, the theoretical basis, working modes, and triboelectric materials are described. Then, TENG devices for vibration energy harvesting are classified and introduced based on the structural characteristics, and the main advantages and disadvantages are compared. Furthermore, the current research progress of a self‐powered vibration monitoring system based on TENG is introduced. Finally, the shortcomings of triboelectric nanogenerators in this field are analyzed and summarized, and future research directions and application scenarios are prospected.
