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.

“…Based on the freestanding mode, Du et al 44 constructed a robust silicone rubber strip-based triboelectric nanogenerator. Wang et al 45 fabricated a novel double-spring-piece structured triboelectric sensor with sensitivity and stability improved by using double longitudinal spring pieces. However, these TENGs with freestanding mode are usually sensitive to vertical vibration and cannot harvest horizontal vibration energy at the same time, which makes them inefficient in harvesting complex vibration energy with multi-directional vibration coupling.…”

Harvesting the vibration energy commonly found in engines, air compressors, and other machines is of great significance for energy recovery and reutilization. However, due to the small vibration amplitude and non-single vibration directions, the conventional vibration energy harvesters based on triboelectric nanogenerators (TENGs) have a low efficiency. In this work, we proposed a TENG with a rotational freestanding mode (RFM-TENG), which can effectively harvest the mechanical vibration energy with a small amplitude, high frequency, and multiple directions. The working principle and performance characteristics of each TENG unit were demonstrated through theoretical analysis and electrical simulations. To further improve the harvest efficiency, we prepared a room-temperature vulcanized silicone rubber (RTV) film doped with high dielectric constant halloysite nanotubes powder as the triboelectric layer, which increased the open-circuit voltage by 100% and the short-circuit current by 85% at an optimal doping ratio of 7 wt %. When the RFM-TENG was installed on an air compressor, it generated an open-circuit voltage of about 60 V and a maximum output power of 45 μW and allowed 30 commercial LEDs to light up simultaneously. RFM-TENG has the advantages of strong nonlinearity, high sensitivity, and multi-directional response and has potential applications in the field of smart factory and digital twin.
