With the rapid development of the Internet of Things (IoT) and the ongoing Fourth Industrial Revolution, the effective conversion of wasted ambient mechanical energy from the environment to generate electricity is regarded as one of the most pivotal technologies for powering widely distributed electronics in the era of the Internet of Things. Although the triboelectric nanogenerator (TENG), based on the coupling effect of contact electrification and electrostatic induction, has recently undergone a tremendous evolution with the development of various features such as flexibility, conformability, and user‐friendliness, further improvement of the output performance is still required for usage toward practical applications for the next‐generation of IoT devices. In this review article, surface nanostructure modification methods for high‐performance triboelectric nanogenerators are systematically summarized. The field is deeply reviewed, with the methods classified into four categories: templating method, appending method, etching method, and crumpling method. Finally, an in‐depth discussion of the existing challenges and the direction of future efforts for enhancing TENG output performance are clearly stated, which can contribute to promoting further development of the field.

The flourishing development of multifunctional flexible electronics cannot leave the beneficial role of nature, which provides continuous inspiration in their material, structural, and functional designs. During the evolution of flexible electronics, some originated from nature, some were even beyond nature, and others were implantable or biodegradable eventually to nature. Therefore, the relationship between flexible electronics and nature is undoubtedly vital since harmony between nature and technology evolution would promote the sustainable development. Herein, materials selection and functionality design for flexible electronics that are mostly inspired from nature are first introduced with certain functionality even beyond nature. Then, frontier advances on flexible electronics including the main individual components (i.e., energy (the power source) and the sensor (the electric load)) are presented from nature, beyond nature, and to nature with the aim of enlightening the harmonious relationship between the modern electronics technology and nature. Finally, critical issues in next-generation flexible electronics are discussed to provide possible solutions and new insights in prospective exploration directions.

In recent years with developing wearable technologies, one of the challenges is energy consumption. Rechargeable or removable batteries are incompatible with wearable applications. Because the batteries are not flexible, foldable, stretchable, lightweight, and require substitutes or charges. Consequently, the best choice is self‐charging systems. The extremely stretchable and washable textile triboelectric nanogenerator (T‐TENG) is designed and fabricated in this work. It is knitted with a rib stitch technique by double twisted thread‐based. Subsequently, the rib stitch method is chosen to achieve the most stretchability and flexibility in this textile by investigating the knitting techniques. Likewise, the active triboelectric materials are polyvinyl chloride and polyamide 6. The maximum instantaneous peak power density is ≈18 mW m‐2 and the measured output voltage and current are 29.2 V and 5.3 μA, respectively. Following this, the experimental test report on the index finger, the relationship between textile tension and voltage production, and the resulting wash and durability tests are provided. This work successfully demonstrates T‐TENG quite compatible with self‐power wearable applications, which can harvest energy from the ambient mechanical tensions and capable of supply power for low power systems in wearable electronics.
