“…Large quantities of vibration energy will inevitably be generated during the operation of large mechanical equipment. , At present, this large mechanical equipment usually has a large number of micro/nanosensors for monitoring various information on the equipment. However, these sensors not only require a sustainable power supply but also have certain requirements on the application space and environment due to their high level of integration.…”

The hybrid of a triboelectric nanogenerator (TENG) and an electromagnetic generator (EMG) has been shown to be an effective approach toward harvesting vibration energy. Therefore, in this work, a triboelectric–electromagnetic hybrid energy harvester based on magnetic liquid is proposed. The magnetic liquid (prepared by Beijing Shenran Magnetic Fluid Co., Ltd) is made with water, an active agent, and ferromagnetic particles. Electrostatic induction between the polymer sidewall and the solvent water activates a triboelectric generator component, while electromagnetic induction between the suspended ferromagnetic particles and an outer coil activates the electromagnetic generator component. Initially, the harvester is deduced theoretically to show the feasibility of the design. Then, the output performance of the energy harvester is fully investigated under various dynamical experiments. Finally, experimental results show that the hybrid energy harvester has very low threshold amplitude and wide operating frequency range, both of which can be particularly advantageous for harvesting subtle and irregular vibrations.

“…Vibration energy is a widespread energy beam, such as rails, wheels, bridges, etc ( Cao et al., 2022 ; Park, 2017 ). Especially for the track vibration, the running speed of the train, the load, the unevenness of the track, the mismatch between the track and the wheels, etc., will cause and excite the track to different degrees of strong vibration ( Qi et al., 2022 ). And the track vibration has strong adaptability to environmental conditions such as weather and temperature.…”

“…That is why energy harvesters have found application in very different fields [ 16 , 17 , 18 ]; see also [ 19 , 20 ]. In particular, vibration energy harvesters, which convert the wide available mechanical energy of vibrations into electric energy, have proven particularly attractive [ 21 , 22 ]. These devices are mainly based on piezoelectric materials or electromagnetic induction [ 23 , 24 ].…”

We study the power extracted by an electromagnetic energy harvester driven by broadband vibrations. We describe the system with a linear model, featuring an underdamped stochastic differential equation for an effective mass in a harmonic potential, coupled electromechanically with the current in the circuit. We compare the characteristic curve (power vs. load resistance) obtained in experiments for several values of the vibration amplitude with the analytical results computed from the model. Then, we focus on a more refined analysis, taking into account the temporal correlations of the current signal and the fluctuations of the extracted power over finite times. We find a very good agreement between the analytical predictions and the experimental data, showing that the linear model with effective parameters can describe the real system, even at the fine level of fluctuations. Our results could be useful in the framework of stochastic thermodynamics applied to energy harvesting systems.
