Self-healing triboelectric nanogenerators (TENGs) with flexibility, robustness, and conformability are highly desirable for promising flexible and wearable devices, which can serve as a durable, stable, and renewable power supply, as well as a self-powered sensor. Herein, an entirely self-healing, flexible, and tailorable TENG is designed as a wearable sensor to monitor human motion, with infrared radiation from skin to promote self-healing after being broken based on thermal effect of infrared radiation. Human skin is a natural infrared radiation emitter, providing favorable conditions for the device to function efficiently. The reversible imine bonds and quadruple hydrogen bonding (UPy) moieties are introduced into polymer networks to construct self-healable electrification layer. UPy-functionalized multiwalled carbon nanotubes are further incorporated into healable polymer to obtain conductive nanocomposite. Driven by the dynamic bonds, the designed and synthesized materials show excellent intrinsic self-healing and shape-tailorable features. Moreover, there is a robust interface bonding in the TENG devices due to the similar healable networks between electrification layer and electrode. The output electric performances of the self-healable TENG devices can almost restore their original state when the damage of the devices occurs. This work presents a novel strategy for flexible devices, contributing to future sustainable energy and wearable electronics.

“…To the best of our knowledge, this is the first TENG that both its triboelectrically charged layer and electrode are inherently healable without the need of heating, high‐transparent, and superstretchable. Besides, the healing time (30 min at 100% efficiency at 900% strain), stretchability, and transparency of the EHTS‐TENG all compare favorably with those of reported partially healable TENGs (Table S1, Supporting Information) . The EHTS‐TENG can generate electricity by touching other materials such as skin, latex, clothing, and so forth.…”

“…Such damage easily occurs in emerging portable/wearable/flexible gadgets. Therefore, developing self‐repairable and deformable TENGs is highly desired . Moreover, considering the use of TENGs for self‐powered tactile sensing in e‐skins/user interfaces/touch screens, transparency is other crucial attribute for visual transmission of information …”

“…Previously, a healable TENG with ≈100%‐strain stretchability was reported by using a dynamic disulfide‐bond‐based triboelectric layer and percolated‐silver‐nanowire (Ag NW) electrode; however, it was not transparent and required heating at 65 °C for hours to recover from damage. Guan et al developed a healable TENG with ≈4%‐strain stretchability through an external healing‐assisting layer; however, the carbon‐based electrode was opaque, and the device was restored when heated over 130 °C. Sun et al used a dynamic imine‐bonded elastomer to develop a transparent triboelectric layer with ≈470% stretchability that was healable at room temperature .…”

Power and electronic components that are self-healable, deformable, transparent, and self-powered are highly desirable for next-generation energy/ electronic/robotic applications. Here, an energy-harvesting triboelectric nanogenerator (TENG) that combines the above features is demonstrated, which can serve not only as a power source but also as self-powered electronic skin. This is the first time that both of the triboelectric-charged layer and electrode of the TENG are intrinsically and autonomously self-healable at ambient conditions. Additionally, comparing with previous partially healable TENGs, its fast healing time (30 min, 100% efficiency at 900% strain), high transparency (88.6%), and inherent superstretchability (>900%) are much more favorable. It consists of a metal-coordinated polymer as the triboelectrically charged layer and hydrogen-bonded ionic gel as the electrode. Even after 500 cuttingand-healing cycles or under extreme 900%-strain, the TENG retains its functionality. The generated electricity can be used directly or stored to power commercial electronics. The TENG is further used as self-powered tactilesensing skin in diverse human-machine interfaces including smart glass, an epidermal controller, and phone panel. This TENG with merits including fast ambient-condition self-healing, high transparency, intrinsic stretchability, and energy-extraction and actively-sensing abilities, can meet wide application needs ranging from deformable/portable/transparent electronics, smart interfaces, to artificial skins.

“…The ability to withstand complex mechanical deformation is limited owing to the Young's modulus mismatch of interface compatibility of triboelectric layer and electrode layer. Recently, there have been three general strategies to make stretchable conductors to match stretchable triboelectric materials such as polydimethylsiloxane (PDMS) or silicone rubber [32]: including deterministic geometries of rigid materials to elongate, dispersing conductive particles in elastomer, and utilizing conductive materials that are intrinsically stretchable [28,[33][34][35]. However, for the stretchable fiber-based power textiles, it is needed to be realized by designing reasonable geometrical shape.…”

HIGHLIGHTS• Owing to the great robustness, continuous conductivity, and geometric construction of a steel wire electrode, the FST-TENGs demonstrate high stability, stretchability, and even tailorability.• By knitting several FST-TENGs to be a fabric or a bracelet worn on the human body, it enables to harvest human motion energy.• The FST-TENGs can also be woven on dorsum of glove to monitor the movements of gesture.ABSTRACT Continuous deforming always leads to the performance degradation of a flexible triboelectric nanogenerator due to the Young's modulus mismatch of different functional layers. In this work, we fabricated a fiber-shaped stretchable and tailorable triboelectric nanogenerator (FST-TENG) based on the geometric construction of a steel wire as electrode and ingenious selection of silicone rubber as triboelectric layer.Owing to the great robustness and continuous conductivity, the FST-TENGs demonstrate high stability, stretchability, and even tailorability. For a single device with ~ 6 cm in length and ~ 3 mm in diameter, the open-circuit voltage of ~ 59.7 V, transferred charge of ~ 23.7 nC, short-circuit current of ~ 2.67 μA and average power of ~ 2.13 μW can be obtained at 2.5 Hz. By knitting several FST-TENGs to be a fabric or a bracelet, it enables to harvest human motion energy and then to drive a wearable electronic device. Finally, it can also be woven on dorsum of glove to monitor the movements of gesture, which can recognize every single finger, different bending angle, and numbers of bent finger by analyzing voltage signals.
