“…In particular, two important limitations of TENGs are their high‐value internal impedance matching and low power density, which remain in wide‐scale commercial use. [ 13,14 ] Few previous studies focused on TENG impedance matching reduction. These studies significantly improved the output power density.…”

Surface modification of triboelectric negative layers is an essential factor for boosting the output performance of triboelectric nanogenerators (TENGs). Herein, a novel scalable surface modification method is introduced using a fabric‐assisted micropatterning technique on a highly negative MXene/silicone nanocomposite surface (charge generating) with MXene layer (charge trapping) for self‐powered sensors and wearable electronics. The microstructured surface is fabricated directly from a fabric template requiring no surface‐active agent, high‐pressure equipment, or high vacuum. To boost the proposed double‐side‐contact TENG (DSC‐TENG) output performance, different parameters of the fabric textures are tested and optimized for the roughened microstructures, namely the MXene layer and relative humidity. Under optimal conditions, the fabricated DSC‐TENG improves the voltage and peak current density by factors of 9.8 and 20, respectively, regarding flat silicone. It exhibits a maximum peak power density of 55.47 W m−2 at load resistance of 0.18 MΩ, and a corresponding decrease in resistance by 75% using MXene content of 3 mg cm−2. Also, DSC‐TENG‐based smart home control of electrical appliances, theft protection, self‐powered electronic devices, password authentication, and human motion monitoring via smartphone for the IoT are demonstrated. The proposed method can be implemented for different types of polymers, thereby enabling the large‐scale fabrication of high‐performance TENGs in industrial applications.

“…Tube‐structured multilayer TENGs have been developed to harvest vibrational energy from tree branches. [ 14 ] Therein, the complicated surface treatment was employed to ensure high power output, which, however, results in a relative high product cost. Easy‐to‐fabricate low‐cost tube‐structured multilayer TENGs with high power output are under exploration in our laboratory.…”

A new sliding triboelectric nanogenerator (TENG) with multiple friction interfaces has been developed. The use of off‐the‐shelf polyethylene terephthalate (PET) and Kapton films as the triboelectric materials, the adoption of cost‐effective flexographic printing as the electrode deposition technique, and the avoidance of expensive and time‐consuming surface treatments render the new TENG easy‐to‐fabricate and inherently low cost. The new sliding TENG generates a surface charge density comparable with the previously reported multilayer sliding TENG whose triboelectric surfaces were modified with expensive and time‐consuming plasma etching for improved triboelectrification. Coupled with the freedom of varying the lateral size and the number of friction interfaces, the new sliding TENG can directly light up hundreds of LEDs, or sustainably power small wearable and portable electronics when integrated with a capacitor through a rectifier. When the new sliding TENG is wrapped around with rubber bands in longitudinal direction, it transforms into a stretchable TENG and is able to harvest energy from tensile motion associated with many human activities.

“…Pang et al. [ 174 ] developed a self‐powered fire alarm system based on a novel multilayered cylindrical triboelectric nanogenerator (MC‐TENG), which could convert the kinetic energy generated by tree shaking collected in the natural environment into electric energy. It is worth mentioning that this system is more suitable for the forest with solid branches due to the fragile crop may not be able to afford the weight of hanging MC‐TENG.…”

The excellent stretchability and biocompatibility of flexible sensors have inspired an emerging field of plant wearables, which enable intimate contact with the plants to continuously monitor the growth status and localized microclimate in real‐time. Plant flexible wearables provide a promising platform for the development of plant phenotype and the construction of intelligent agriculture via monitoring and regulating the critical physiological parameters and microclimate of plants. Here, the emerging applications of plant flexible wearables together with their pros and cons from four aspects, including physiological indicators, surrounding environment, crop quality, and active control of growth, are highlighted. Self‐powered energy supply systems and signal transmission mechanisms are also elucidated. Furthermore, the future opportunities and challenges of plant wearables are discussed in detail.
