“…To improve the performance of TENGs, numerous efforts have been made in various aspects, including multilayer-stacked structures [39][40][41][42][43][44][45][46][47][48][49][50][51][52], nanostructured surface modifications [53][54][55], contact material synthesis [56,57], optimization of surface charge density [58][59][60], advanced mechanical design [61][62][63][64][65], novel manufacture approaches and power management circuit design [66][67][68]. Among these, multilayer-stacked TENG has been regarded as one of the most effective and simple methods to maximize the instantaneous output power by synchronizing all the layers of TENGs.…”

Flexible, compact, lightweight and sustainable power sources are indispensable for modern wearable and personal electronics and small-unmanned aerial vehicles (UAVs). Hierarchical honeycomb has the unique merits of compact mesostructures, excellent energy absorption properties and considerable weight to strength ratios. Herein, a honeycomb-inspired triboelectric nanogenerator (h-TENG) is proposed for biomechanical and UAV morphing wing energy harvesting based on contact triboelectrification wavy surface of cellular honeycomb structure. The wavy surface comprises a multilayered thin film structure (combining polyethylene terephthalate, silver nanowires and fluorinated ethylene propylene) fabricated through high-temperature thermoplastic molding and wafer-level bonding process. With superior synchronization of large amounts of energy generation units with honeycomb cells, the manufactured h-TENG prototype produces the maximum instantaneous open-circuit voltage, short-circuit current and output power of 1207 V, 68.5 μA and 12.4 mW, respectively, corresponding to a remarkable peak power density of 0.275 mW cm−3 (or 2.48 mW g−1) under hand pressing excitations. Attributed to the excellent elastic property of self-rebounding honeycomb structure, the flexible and transparent h-TENG can be easily pressed, bent and integrated into shoes for real-time insole plantar pressure mapping. The lightweight and compact h-TENG is further installed into a morphing wing of small UAVs for efficiently converting the flapping energy of ailerons into electricity for the first time. This research demonstrates this new conceptualizing single h-TENG device's versatility and viability for broad-range real-world application scenarios.

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.

“…In the past few years, there have been many HMI prototypes reported by using triboelectric mechanisms. [ 16,25,31,35,39–41 ] The self‐powered signal outputs of TENGs are mainly based on the contact‐separation triboelectric mode or lateral‐sliding triboelectric mode. [ 42–44 ] The contact‐separation triboelectric mode sensing is usually implemented by pressure or tactile motions.…”

in diverse application fields, for example, entertainment, robotics, [3] virtual reality/ augmented reality (VR/AR), [4] smart factory, and so on. [5-7] Beyond that, HMI can even be extended to medical rehabilitation, [8] extreme environmental operation, [9] remote education, telemedicine, and other fields. [10,11] With the aid of technology advance, the effectiveness and intuitiveness of interaction are more demanding. The solutions of HMI are switching from the conventional control terminals, such as keyboard, touchpad, and joystick, toward more diversified and creative alternatives. As a result, many new interaction mechanisms have been developed to satisfy the need for efficient and intuitive interaction. [12] For instance, vision recognition can identify facial features and realize human motion capture to complete motion mapping. [13,14] Evolving together with the fast-growth of wearable electronics and IoT, modern HMI are developing toward self-powered capability [15-17] and flexible wearable compatibility. [12] Self-powered electronics are of increasing importance due to their environmentally friendly and self-sustainability, providing an possible solution in alleviating the global energy crisis and environmental pollution. [18-22] Many self-powered electronics have been developed by integrating different energy harvesting technologies, such as electromagnetic, [18-20] piezoelectric, [21,22] and triboelectric. [17,18,23-26]. Based on the coupling of triboelectrification and electrostatic induction, triboelectric nanogenerators (TENGs) have been demonstrated as promising candidates [27-33] for various selfpowered sensing or self-driven controlling [16,17,25] applications. For example, Luo reported a flexible and durable wood-based TENG for self-powered sensing in athletic big data analytics. [34] It can be used to smart sport monitoring and assisting. It also can be used to promote the development of big data analytics in intelligent sports industry. TENG-based self-powered technology provides a creative way to realize HMI [35,36] because of its superior advantages such as self-generated signals, high output sensitivity, simple but diverse configurations, low cost, various material applicability, and flexibility. [34,37,38] In the past few years, there have been many HMI prototypes reported by using triboelectric mechanisms. [16,25,31,35,39-41] In recent years, human-machine interface technology has entered a period of rapid development in the global scope. It has gradually expanded from the initial field of medical rehabilitation to engineering bionics, virtual reality, space technology, deep-sea assignments, atomic energy technology, remote education, and other areas. Herein, an innovative, self-powered delta-parallel human-machine interface (DT-HMI) for 3D sensing and control is proposed. By using three pairs of triboelectric nanogenerator (TENG) sensing gears based on both contact-separation and sliding modes of triboelectric effect, the positive and negative rotation of the gears and rotation angles ca...
