It is of great significance to establish a low-cost, highefficiency, self-powered micrometeorological monitoring system for agriculture, animal husbandry, and transportation. However, each additional detection element in the meteorological monitoring system increases the power consumption of the whole system by about 0.7 W. As a renewable energy technology, a triboelectric nanogenerator has the advantages of low price and self-powered sensing. To reduce the power consumption of the micrometeorological monitoring system, this work introduces an innovative solution: the wind-gathering enhanced triboelectric-electromagnetic hybrid generator (WGE-TEHG). Coupling the thin-film vibrating triboelectric nanogenerator (TENG) and electromagnetic generator (EMG), the TENG is used to monitor wind direction and the EMG is used to monitor wind speed and provide energy needed by the system. In particular, the TENG can be used as a self-powered sensor to reduce the power consumption of the sensing system. Besides, the TENG is used to produce slit effect to enhance the output performance of EMG. The experimental results show that the WGE-TEHG can build a self-powered natural environment micrometeorological sensing system. It can monitor the wind direction, wind speed, temperature, and relative humidity. This research has great application value for the self-powered sensing implementation of a hybrid TENG and EMG.

“…3 In 2012, Z. L. Wang et al first invented a triboelectric nanogenerator (TENG) based on the coupling of TE and electrostatic induction (EI), 4 which has attracted extensive attention thanks to its unique merits of low cost, lightweight, diverse material selection, ecofriendliness, and high-efficiency for HEE harvesting. [5][6][7][8][9] TE, EI, and electrostatic breakdown (EB) are the fundamental working mechanisms of TENGs to harvest energy from the surrounding environment. Based on the three basic mechanisms, different types of TENGs have been developed, which could be categorized into three types according to the output characteristics: ordinary alternating current TENGs (AC-TENGs), direct current TENGs (DC-TENGs), and dualfunctional TENGs (DF-TENGs).…”

“…[11,12] Over the past few years, the assortment of multifunctional soft iontronic devices based on hydrogel/ionogel electrodes have been demonstrated, such as electronic skins, [13][14][15][16] artificial muscles and axons, [17][18][19] AC luminous devices, [20][21][22] liquid crystal devices, [23,24] flexible ionic diodes, [25,26] and triboelectric nanogenerators (TENG). [27][28][29] Nevertheless, the breakdown of hydrogel iontronic devices under electrified conditions should be sufficiently considered. Since hydrogel iontronic devices rely on both mobile ions and mobile electrons, their breakdown behaviors are far more complex than traditional electrical breakdowns.…”

Soft hydrogel iontronic devices, utilizing the assumed non‐Faradaic exchange of ions and electrons at the metal‐hydrogel interfaces, have been demonstrated with advantages of high stretchability, transparency, and biocompatibility. Yet, in real situation under high voltage, Faradaic reaction is inevitable, which can breakdown the device and lead to the low durability. Herein, the Faradaic breakdown behaviors of hydrogel iontronic devices under high AC voltage are systematically studied. Side reactions including electrode corrosion and water electrolysis are confirmed in the electrical double layer. Interface barrier layers are proposed to eliminate this issue. It is found that acetylene black (ACET) as modification layer can achieve the best performances, providing effective protection while maintaining the electrical performances. By leveraging ACET‐modified electrodes, long‐term durable iontronics, including electroluminescent devices and high‐output triboelectric nanogenerators, are successfully demonstrated. This work can provide insightful strategies for developing practical hydrogel iontronic devices.
