As the world is marching into the era of the internet of things (IoTs) and artificial intelligence, the most vital development for hardware is a multifunctional array of sensing systems, which forms the foundation of the fourth industrial revolution toward an intelligent world. Given the need for mobility of these multitudes of sensors, the success of the IoTs calls for distributed energy sources, which can be provided by solar, thermal, wind, and mechanical triggering/vibrations. The triboelectric nanogenerator (TENG) for mechanical energy harvesting developed by Z.L. Wang's group is one of the best choices for this energy for the new era, since triboelectrification is a universal and ubiquitous effect with an abundant choice of materials. The development of self‐powered active sensors enabled by TENGs is revolutionary compared to externally powered passive sensors, similar to the advance from wired to wireless communication. In this paper, the fundamental theory, experiments, and applications of TENGs are reviewed as a foundation of the energy for the new era with four major application fields: micro/nano power sources, self‐powered sensors, large‐scale blue energy, and direct high‐voltage power sources. A roadmap is proposed for the research and commercialization of TENG in the next 10 years.

to drive many small electronic devices or serve as self-powered sensors. [11][12][13][14] Its rapid development is reshaping our inherent understanding of energy harvesting technologies.As an emerging power in the field of selfpowered technology, the wearable TENGs are showing vigorous development vitality and giant application potential due to its simple configuration, light weight, low cost, output stability, and eco-friendly feature. [15,16] However, wearable devices will generally direct contact on the skin surface of the human body. While ensuring the stable output, the wearable TENG also requires excellent flexibility, portability, and breathability to improve human comfort during long-term use. [17][18][19][20] The traditional wearable TENGs are mostly assembled from the dense films that involve complex physical and chemical processes, which results in a high manufacturing cost and is hard to balance the physiological needs of human comfort. [21][22][23][24][25] There are still challenges in developing a wearable TENG that combines flexibility and breathability.The electrospun technique is one of the feasible preparation routes for TENG that assembled from the nanofiber films. [26][27][28][29][30][31] As an ideal triboelectric material, the nanofiber is attracting extensive attention due to its high specific surface area and excellent flexibility. Moreover, the porous structure gives it good breathability and ultra-lightweight. [32][33][34][35][36] And the nanofiber can be electrospun from various polymer materials, while the modification method and structural design are simple and diverse. [37,38] In addition, the Janus films could be fabricated via the electrospun method, which will combinate the advantages of Janus structure and electrospun nanofiber. The Janus films will provide asymmetric properties on each side with its own integrity (such as morphology, conductivity, and hydrophilicity). [39] Therefore, the dual-functional nanofiber films exhibit various potential applications, especially in the field of wearable electronics. [40][41][42][43] It is interesting and meaningful to fabricate a flexible and breathable TENG by the Janus films, the nanofiberbased TENG can be used as a wearable health-monitoring system or a self-powered supply source to directly attach at the skin surface and provide long-term comfort.Here, we first developed an all-nanofiber-based wearable TENG which is completely constructed from the Janus nanofiber films for energy harvesting and self-powered sensing.The traditional wearable nanogenerators are mostly assembled from the dense films that involve complex physical and chemical processes, which results in a high manufacturing cost and is hard to balance the physiological needs of human comfort.

Human–machine interfaces are essential components between various human and machine interactions such as entertainment, robotics control, smart home, virtual/augmented reality, etc. Recently, various triboelectric‐based interfaces have been developed toward flexible wearable and battery‐less applications. However, most of them exhibit complicated structures and a large number of electrodes for multidirectional control. Herein, a bio‐inspired spider‐net‐coding (BISNC) interface with great flexibility, scalability, and single‐electrode output is proposed, through connecting information‐coding electrodes into a single triboelectric electrode. Two types of coding designs are investigated, i.e., information coding by large/small electrode width (L/S coding) and information coding with/without electrode at a predefined position (0/1 coding). The BISNC interface shows high scalability with a single electrode for detection and/or control of multiple directions, by detecting different output signal patterns. In addition, it also has excellent reliability and robustness in actual usage scenarios, since recognition of signal patterns is in regardless of absolute amplitude and thereby not affected by sliding speed/force, humidity, etc. Based on the spider‐net‐coding concept, single‐electrode interfaces for multidirectional 3D control, security code systems, and flexible wearable electronics are successfully developed, indicating the great potentials of this technology in diversified applications such as human–machine interaction, virtual/augmented reality, security, robotics, Internet of Things, etc.
