“…For example, a tube-like, siliconebased TENG that can be installed under the shoe or on clothing was developed to harvest electrical energy from human walking for powering wearable electronics such as watches and fitness trackers. [81] The ultrastetchable, skin-like TENG (STENG) had a sandwich-like architecture with a layer of ionic hydrogel encapsulated between two elastomer films ( Figure 8b). [80] The conductive liquid, such as sodium chloride solution, was encapsulated in the soft rubber, and the fabricated device could stand a tensile strain up to 300% without obvious degradation even after ≈55k deformation cycles.…”

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.

“…Thus, the construction of flexible, wearable, highly sensitive, and lightweight FTSs based on rGO is a top priority. The integration of energy harvest, storage, and conversion into a single configuration has attracted abundant attention in recent years 34, 35, 36, 37, 38. Our target in adopting this strategy is to integrate FTSs with FASCs to fabricate a device that can provide stable output power to FTSs.…”

Wearable fiber‐shaped electronic devices have drawn abundant attention in scientific research fields, and tremendous efforts are dedicated to the development of various fiber‐shaped devices that possess sufficient flexibility. However, most studies suffer from persistent limitations in fabrication cost, efficiency, the preparation procedure, and scalability that impede their practical application in flexible and wearable fields. In this study, a simple, low‐cost 3D printing method capable of high manufacturing efficiency, scalability, and complexity capability to fabricate a fiber‐shaped integrated device that combines printed fiber‐shaped temperature sensors (FTSs) with printed fiber‐shaped asymmetric supercapacitors (FASCs) is developed. The FASCs device can provide stable output power to FTSs. Moreover, the temperature responsivity of the integrated device is 1.95% °C−1.

“…Figure 2b,c displays the acquired voltage and current time profile of the smart carpet in the press and release states, respectively. [39,40] The proper pairs and rough surface promise the high sensitivity. As a pressure sensor, the TENG textile should be sensitive to the externally applied pressure.…”

solitude and the first time to help patients are becoming increasingly important and exigent. Fortunately, the development of science and technology has made this urgent demand no longer out of reach. [5] Over the past few decades, three mainstream fall monitoring methods have been developed, including vision-based, [6,7] ambient-based technologies, [8,9] and wearable-based, [10][11][12] according to the type and position of sensors that are installed in the systems. However, in the course of use, these methods
