“…The cantilever beam structure is very common in piezoelectric generator. [113,114] The cantilever beam is fixed at one end and a mass block is attached at the other end. Under the external excitation, the cantilever beam undergoes upward and downward displacement deformation, which deforms the piezoelectric element on the cantilever and thus form piezoelectric generator.…”

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.

“…[1][2][3] Concurrently, the recent advancements in self-powered electronics and the demands for moveable, lightweight, and isolated instruments have spurred investigations into various types of energy harvesters. [4][5][6][7][8][9][10][11] These devices transform naturally existing energy in the environment, such as mechanical vibration, light, heat, and electromagnetic radiation, into a useful form. [12][13][14][15] Among these potential environmental sources, wind energy appears to be prominent due to its high kinetic energy potential and widely recognized utilization, dating back to early sailboats around 3500 BC.…”

Flow‐induced vibrations are common occurrences in various fluid–solid interaction systems existing in nature. One way to transform this vibrational mechanical energy into a usable form is through energy harvesters. This study examines the performance of a piezoelectric energy harvester, where mechanical oscillations result from the fluttering flags made of various fabrics. Flags, made of commonly encountered fabrics, are attached to a cantilever beam inside a wind tunnel with a 30 × 30 cm test section, allowing the airflow to be adjusted between 0 and 10 m s−1. The alpaca flag, with dimensions corresponding to an aspect ratio of 2, can produce meaningful electricity even at a wind speed as low as ≈3.8 m s−1. As the wind speed increases, the fluttering frequency of this flag configuration becomes 10.9 Hz at a wind speed of 5 m s−1, coinciding with the natural frequency of the first mode shape. In this specific arrangement, the structural deformation of the piezoelectric patch on the beam surface is maximized, allowing the harvester system to produce a root mean square voltage of 5 V with a relatively high maximum power of 98 μW.
