With the rapid development of industry and information technology, rough challenges have been put forward for the traditional sensor technology to meet the increasingly complex and diverse application demands in actual production and daily life, and the widely distributed sensor network also faces complex power supply and maintenance problems. As a new energy conversion technology, triboelectric nanogenerators (TENGs) based on triboelectrification and electrostatic induction effect can respond to the weak mechanical stimuli in the surrounding environment and generate corresponding electrical signals to realize the sensing function without external power supply. In addition, TENGs have the advantages of wide selection of fabrication materials, flexible and diverse fundamental modes, which can be customized for different applications and realize different sensing functions. In recent years, triboelectric sensors based on TENGs have developed rapidly, and researchers have developed variable triboelectric sensors for different application scenarios. In this paper, the developed triboelectric sensos have been classified into different categories, the advanced strategy to prepare advanced triboelectric materials and technology used for manufacturing integration have been introduced. This work summarizes the main applications of triboelectric sensors and put forward the current challenges, so as to provide guidance and instructions for the future development of triboelectric sensors.

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.

Triboelectric‐electromagnetic hybrid nanogenerator (TEHG) has emerged as a promising technology for distributed energy harvesting. However, currently reported hybrid generators are straightforward combinations of two functional components. Moreover, inevitable heat from friction intensifies material abrasion and degrades the performance of polymer‐based triboelectric nanogenerators (TENGs). Here, a self‐reinforcing TEHG that harnesses the magnetocaloric and magnetization effects of gadolinium (Gd) is proposed. The synergy between TENG and electromagnetic generator (EMG) renders them an indivisible unit. Leveraging Gd's magnetocaloric effect, an efficient heat transfer mechanism is constructed to cool the tribolayer and strengthen the device's electrical stability. After 80 hours of continuous operation, the optimized TENG occupies a charge decay rate of only 0.32% per hour, significantly outperforming most existing TENGs. Additionally, Gd's magnetization effect boosts the power of EMG by approximately 80.84%. This work provides a universal solution in hybrid generators where internal components reinforce each other, achieving a synergistic effect of 1+1>2.This article is protected by copyright.
