“…Particularly, flexible TENGs are often utilized as angle sensors to monitor elbow or knee bending. [ 45–48 ] Compared to bare hydrogel sensors, the H‐TENG strain sensors can not only power electronics based on the voltage signals, protect the inside hydrogel from being contaminated/damaged, but also retard its water loss and further be utilized in wearable applications. The high flexibility and stretchability of hydrogels also provide suitability as electrodes in TENGs for motion energy harvesting requiring high strain values, which are unique advantages that other flexible electrodes can not achieve.…”

Flexible triboelectric nanogenerators (TENGs) have attracted increasing interest since their advent in 2012. In comparison with other flexible electrodes, hydrogels possess transparency, stretchability, biocompatibility, and tunable ionic conductivity, which together provide great potential as current collectors in TENGs for wearable applications. The development of hydrogel-based TENGs (H-TENGs) is currently a burgeoning field but research efforts have lagged behind those of other common flexible TENGs. In order to spur research and development of this important area, a comprehensive review that summarizes recent advances and challenges of H-TENGs will be very useful to researchers and engineers in this emerging field. Herein, the advantages and types of hydrogels as soft ionic conductors in TENGs are presented, followed by detailed descriptions of the advanced functions, enhanced output performance, as well as flexible and wearable applications of H-TENGs. Finally, the challenges and prospects of H-TENGs are discussed.

“…However, limited by the current synthesis routes and techniques, it's relatively difficult for the SACs to possess sufficient atom loading. Recent years have witnessed fruitful advancements in introducing other active sites/moieties such as nanoparticles and vacancies [86–88] into the SAC supports to construct a novel electrocatalyst system. These well‐designed catalyst systems integrate the local isolated metal atoms and the foreign active centers to pledge the reaction efficiency of the whole cathode.…”

On account of high energy density and low cost of sulfur, lithium‐sulfur (Li−S) battery has been regarded as an appealing energy storage system to date. Nevertheless, it has faced formidable challenges, mainly pertaining to the fatal shuttle effect and retarded sulfur redox kinetics. Single atom catalysts (SACs) have showcased great promise for addressing these issues owing to their maximum atom utilization efficiency, favorable catalytic activity as well as their good structural tunability at an atomic level, considerably contributing to the recent fruitful advancements in Li−S realm. In this review, we summarize the state‐of‐the‐art strategies in the coordination manipulations of SACs toward highly efficient and durable Li−S batteries. The recent advances, existing issues, and future outlooks are discussed accordingly, aiming to guide the synthetic design of SACs, propel the underlying mechanism understanding and ultimately boost the commercial viability of Li−S batteries.

“…have proposed a stretchable and shape‐adaptive TENG based on potassium iodide and glycerol (KI‐Gly) liquid electrolyte ( Figure 3 a). [ 90 ] The low Young's modulus of this material endows the stretchability of ≈300% for the fabricated TENG device and the output performance can maintain under 250% tension stretching for 10 000 cycles. Due to the shape‐adaptive capability and stretchability, this bulk device can be worn on different body parts, e.g., knee, elbow, and wrist, to harvest human motion energy through bending and releasing process.…”

as the components of the IoT network, and they will generate massive data with multidimensions, higher velocity, and improved heterogeneity. [2] Benefiting from this, our world is developing toward a smarter and more well-knit green earth, covering essential blocks like smart homes, smart agriculture, smart cities, smart industries as well as outer space and airlines. [3] In the green earth, the IoT systems are promising to be spread in every smart area, consisting of various sensing modules, signal processing modules, power management modules, power supply modules, etc. Sensing modules are applied to collect abundant information from the target objects or environment, such as temperature, humidity, light intensity, gas concentration, pressure, etc. And the signal processing modules help with the data transmission, processing, and analysis to connect and exchange information with other devices or systems to provide an optimal command to the target object or environment. In addition, the power management modules and power supply modules are to provide the most efficient solutions to reduce the overall power consumption in the operations of the IoT systems. [4][5][6] Thus, looking at the whole earth, it is to be closely connected with the IoT systems, enabling information transfer and communication over the strong network.Narrowing down to a single object like the human body, a single animal, or a robot, wearable electronics have attracted increasing research interest owing to their promising applications in real-time and precious monitoring and tracking of user's preferences and habits on the green earth. [7][8][9][10] Conventional wearable electronics involve smart watches, smart glasses, smart helmets, etc., while most of them are fabricated from nonflexible or rigid materials, resulting in limited wearable comfort, device lifetime, latency response, and loss of sensing information. [11][12][13] To address these issues, the current research focuses on the investigation of sensing materials with flexibility or even stretchability, breathability, washability, lightweight, adhesiveness, etc., enabling improved wearing comfort and long-term wearability. [14][15][16][17] Besides the wearability of the modules in the IoT system, energy issue is within wide research interest and concern as one of the urgent issues contemporarily. Batteries, as the dominant choices for power supply modules, are now revealed asThe advancement of the Internet of Things/5G infrastructure requires a lowcost ubiquitous sensory network to realize an autonomous system for information collection and processing, aiming at diversified applications ranging from healthcare, smart home, industry 4.0 to environmental monitoring. The triboelectric nanogenerator (TENG) is considered the most promising technology due to its self-powered, cost-effective, and highly customizable advantages. Through the use of wearable electronic devices, advanced TENG technology is developed as a core technology enabling self-powered sensors, power supplies, and data comm...
