“…[ 25 ] In view of their outstanding metallic electrical conductivity, MXenes have become competitive electrode materials in TENGs recently. [ 26 ] Owing to the terminating functional groups containing oxygen and abundant F groups, MXenes are triboelectrically more negative than polytetrafluoroethylene (PTFE), [ 27 ] which makes them function as appropriate negative triboelectric materials in TENGs.…”

“…In view of superior electrical conductivity and high electronegativity of MXenes, an elastic fabric fiber was coated with MXenes and Ag nanoparticles. [ 26 ] This work investigated the effect of the MXene ink coating cycles on the fiber resistance, and concluded that the increase of coating cycles (<6) decreased the fiber resistance significantly. The single‐fiber‐based TENG, in which this fiber acted as the electrode and PDMS acted as the triboelectric layer, exhibited excellent flexibility, stretchability, and mechanical robustness.…”

The integration of triboelectric nanogenerators (TENGs) and 2D nanomaterials brings about 2D‐nanomaterial‐based TENGs (2D‐TENGs) that promote the rapid development of self‐powered sensing systems and wearable electronics. Extraordinary physical, electronic, chemical, and optical properties of 2D nanomaterials endow 2D‐TENGs with improved output performance. This review presents the state of the art of 2D‐TENGs with respect to basic classifications, enhancement mechanisms, special advantages, output performances, and applications in energy harvesting and self‐powered sensing. Furthermore, several challenges that can impede applications of 2D‐TENGs are discussed.

“…[ 9 ] For example, one major energy source in the environment is raining energy since it often rains in many areas, many endeavors have been made to acquire electricity in rainy weather, such as our recent work of a multifunctional TENG yarn in the application of agricultural greenhouse cloth for harvesting raining energy. [ 10 ] Therefore, this requires stable operation of TENG devices in contact with water for a long time. In other words, some specific properties of the material for TENG device are more demanding, including the corrosion resistance of the triboelectric layer and the conductive electrode that is easily corroded.…”

The durability issue of triboelectric nanogenerators (TENGs) still limits its practical application for long‐term operation, especially in harvesting water energy, which is one of the most widespread energies in nature. Attempting to ameliorate this, fluorinated graphene (FG) with unique triboelectric negativity and superhydrophobic property is introduced to serve as a new triboelectric and protective layer for TENG construction. The self‐cleaning as well as anti‐corrosion property and durability of the FG coating‐enabled TENG device is then demonstrated. Furthermore, this novel triboelectronegative material candidate is applied for consecutively coating on Cu mesh and the inner wall of sewage pipe to fabricate TENGs for water energy harvesting and working as a metal protective layer in the meantime. Through the extraordinary output performance, the feasibility of FG‐enabled triboelectric coating to be used in the field of interference screening, filtering, and sewage pipes is proved. This developed triboelectronegative coating not only broadens the material selection of TENG but also significantly enhances the durability and robustness of TENG for water energy harvesting, which possesses great potential in applying in metal protection and water energy harvesting under extreme conditions (e.g., strong acid and strong alkaline environments).

Technological evolution has brought great changes to traditional industries. Nowadays farmers obtain great benefits such as intelligent production and convenient management from intelligent agriculture. Nevertheless, there still exists many flaws in current solutions. Deficiencies in energy management, data transmission and privacy preservation are supposed to be solved. In this paper, the privacy preserved cyber-physical searching framework is proposed to tackle these problems. This four-layer framework can provide a convenient way for farmers to manage production by simply searching for information they interested in. The data source layer contains many sensors for data collection. The data aggregation layer consists of data aggregation nodes deployed in the farms. The data transfer layer employs drones for retrieving data from data aggregation nodes. The cloud control layer is responsible for searching requests processing and privacy preservation. To realize better data collection and searching. The information centric network is introduced into this framework. Moreover, some methods are employed for privacy preservation. The simulation results show the feasibility of this framework.
