“…The bromine-functionalized MOF produces high output with PVDF as the opposite layer compared with its non-bromine-containing counterparts due to enhanced charge transport capability (Zhai et al, 2020). Similarly, fluorinated MOF can behave as high tribonegative materials (Guo et al, 2020). The nontoxic MOFs with no harmful effects on the environment and biological systems are critical for sustainable development.…”

Metal-organic frameworks (MOFs) are multifunctional materials with a unique advantage of high porosity and surface area and size tunability and can be modified without altering the topology. The interesting and desirable properties of MOFs led to their exploration for the triboelectric nanogenerator. Herein, a biodegradable MOF MIL-88A for TENG (MIL-TENG) is reported. MIL-88A can be easily synthesized by coordinating iron chloride and fumaric acid in water, thus offering eco-friendly synthesis. Various materials are selected as opposite layers to MIL-88A to analyze triboelectric behavior and performance. The MIL-TENG exhibits an output trend of TENG EC < TENG Kapton < TENG FEP. The MIL-88A and FEP generated an output voltage of 80 V and an output current of 2.2 mA. The surface potential measurement and electrical output trend suggest the positive triboelectric behavior of MIL-88A concerning FEP and Kapton. The utilization of biomechanical motions and numerous low-rating electronics powered via a capacitor are demonstrated.

“…Furthermore, physical and chemical modifications of triboelectric materials and contact surfaces have also been successfully implemented in this regard. For instance, composite material structures have been used for fabric-based TENG developments, obtaining higher triboelectric charging ( Bai et al., 2019 ; Guo et al., 2020 ; Liu et al., 2020a , 2020b ). Similarly, constructing surface patterning on fabrics ( Choi et al., 2017 ; Huang et al., 2019 ; Paosangthong et al., 2019b ; Zhang et al., 2019 ) (e.g., grated or corrugated structures, reactive ion etching) and the use of nanomaterials and nanopatterning techniques to enhance triboelectric contact area ( Lee et al., 2015 ; Xiong et al., 2018 ) were successfully implemented to improve triboelectric charge density, thus enhancing TENG outputs.…”

Summary Triboelectric nanogenerator (TENG) is an upcoming technology to harvest energy from ambient movements. A major focus herein is harvesting energy from human movements through wearable TENGs, which are constructed by integrating nanogenerators into clothing or accessories. Textile-based TENGs, which include fiber, yarn, and fabric-based TENG structures, account for the majority of wearable TENGs, with many designs and applications demonstrated recently. This calls for a comprehensive analysis of textile-based TENG technology, and how the state-of-the-art device optimization concepts can be deployed to construct them efficiently. Concurrently, how advanced engineering concepts and industrial manufacturing techniques, which are bound with fiber, yarn, and fabric-related developments, can be applied into the TENG context for their output enhancement is still under investigation. Herein, we fill this vital gap by analyzing the state-of-the-art developments, upcoming trends, output optimization strategies, scalability, and prospects of the textile-based TENG technology, presenting a textile engineering perspective.

“…Yu et al 259 extended the properties modification from the surface to the bulk of the triboelectric material by sequential infiltration synthesis. Moreover, filling high-dielectric-constant materials (eg, ceramic material, 72,148 ferroelectric materials, 88,149 piezoelectric material, 150,151 carbon-based materials, 152,153 MOFs, 154,155 and metal nanoparticles, 71,95 etc.) into the target triboelectric material could effectively improve its intrinsic dielectric properties and the TENG output.…”

The ability of future electronics to derive operational power from the working environment is attractive for realizing self-powered unattended electronics. Triboelectric nanogenerator (TENG) effectively harvests the otherwise wasted ubiquitous mechanical energy. Despite the recent advances in the design and development of various triboelectric devices, these devices' output still falls short in meeting the practical needs of directly powering electronics and sensors. Here, we review the recent progress in the design and optimization strategies for improving the TENG output performance, including but not limited to theoretical simulation, materials engineering, device engineering, and power management. The ubiquitous applications of the TENGs in micro/high-voltage power source, multifunctional intelligence, blue energy harvesting, and selfpowered electrochemical system are also discussed. Finally, we provide our perspectives regarding the challenges and opportunities for the future development of triboelectric devices with engineered high-performance and designer functionalities.
