Developing an applicable triboelectric nanogenerator (TENG) for train wheel energy harvesting is a key step to meet the urgent need of wheel safety monitoring. Herein, an innovative design of free‐fixed TENG (FF‐TENG) is reported, without a serious negative impact on the wheel. The key of this design is the magnets fixed on the device and bogie, providing attractive force to immobilize the stator. With a rotational structure, FF‐TENG can provide a high short‐circuit current of 55 µA, an open‐circuit voltage of 500 V, and a charge of 235 nC at a rotation speed of 400 rpm. At an external load resistance of 10 MΩ, FF‐TENG delivers the maximum power of 15.68 mW. Furthermore, the superior robustness of FF‐TENG in vibration environment is proved. In addition, a power management circuit designed by LTC 3588 is tested for more efficient capacitor charging, leading to better performance to power electronics. Finally, a self‐powered real‐time wheel temperature and wheel speed monitoring system is developed with FF‐TENG as a safety alert demo for feasibility demonstration. Given the rational structure design and high performance, this work paves a practical way for TENGs in the field of intelligent transportation.

“…Wave energy, especially ocean/water wave energy(also called blue energy), is abundant and extensive, which is quite challenging to collect through EMG for low-frequency and irregular amplitude. It is necessary to design an efficient, environmentally friendly and inexpensive wave energy harvesting technology ( Chen et al, 2020 ; Shao et al., 2017 ; Yang et al., 2019 ; Yang et al., 2020 ). The structural design is particularly important to make great use of wave energy in our environment.…”

Summary Solar and wind energy harvesting technology is increasingly an economical and efficient energy form and receives excellent support from government policies worldwide. Various functional and structural nanogenerators based on multi-effects named hybridized nanogenerators have been reported separately or simultaneously to effectively generate the wasted mechanical and solar energy in our daily life. We review the development of hybridized nanogenerators, including the working mechanism of solar and mechanical energies. Moreover, the classification of nanogenerators for scavenging mechanical and solar energies is discussed. The potential applications of hybridized nanogenerators are reviewed. Finally, the challenge and prospective of hybridized nanogenerators and the future explored improvements of output performance, stability, preparation, large-scale utilizing, and efficiency are discussed. The hybridized nanogenerator as the energy technology will be popularized in energy and self-powered sensor systems.

“…This hybridized nanogenerator design combines the advantages of the high electromechanical conversion efficiency of the chaotic pendulum and its low operating frequency. The EMG power output is equivalent to 1.23 mW, whereas the TENG's maximum output power is up to 15.21 mW, and the mechanism is inspired by the water waves (Chen et al, 2020a).…”

As the world's demand for alternative energy increases, the development of green energy harvesters becomes ever more important. As a result, the creation of triboelectric (TENG), piezoelectric (PENG), and pyroelectric nanogenerators, electromagnetic generators (EMG), solar cells, and electrochemical cells is attracting interest in an effort to convert mechanical, thermal, magnetic, solar, and chemical energy into electricity. In order to take advantage of the ambient energies from our surrounding environment, the design of hybridized generator units that can simultaneously scavenge energy in a variety of forms continues to develop. These systems are being considered to satisfy the energy needs of a range of electronic devices and adapt to a variety of working environments. This review demonstrates the latest progress in hybridized nanogenerators in accordance with their structure, operating principle, and applications. These studies demonstrate new approaches to developing hybrid techniques and novel assemblies for efficiently harvesting environmental energy from a number of sources.
