“…1e, f and 4a, b). This was consistent with previous literature showing that vertical contact-separation mode TENG usually exhibited asymmetric output characteristics between the output positive and negative voltage and current peaks, 46–50 and this phenomenon could be attributed to the lag of the charge transfer cycle relative to the periodic movement cycle and/or impulsive separation caused by inherent adhesion between the triboelectric surfaces. 46,50 Fortunately, these issues can be alleviated by the optimization of TENG structure parameters ( e.g.…”

“…46,50 Fortunately, these issues can be alleviated by the optimization of TENG structure parameters (e.g., dielectric film thickness) or by the adoption of a power management circuit. [47][48][49] Further investigations on asymmetry output characteristics are currently underway to gain deeper insights into the underlying mechanisms governing the performance of TENG. These results exemplify that the NDSB modification layer is generally applicable to both the dielectric layer and electrode layer in TENG.…”

Due to the advantages of excellent output power, low cost and easily preparation, triboelectric nanogenerator is developing rapidly in the field of renewable energy. The output performance of triboelectric nanogenerator is largely dependent on the surface charge density, which is closely related to the ability of the tribo-material to gain or lose electrons. To obtain higher output power, numerous efforts have been done on material modifications of the friction layer and electrodes of triboelectric nanogenerator with additional fillers or molecular modifications. In this review, advanced materials for the preparation of triboelectric nanogenerator devices to achieve high output, humidity-resisting and wear-resisting performance are presented and the working mechanisms of performance optimisation are discussed. Moreover, natural materials, recyclable materials and non-conventional electrode materials are mentioned to inspire subsequent research on triboelectric nanogenerator.

Rapid advancements in the Internet of Things (IoT) have revolutionized the world by creating a proliferation of low-power wireless devices and sensor nodes. The issue of powering these devices remains a challenge as they require regulated direct current (DC) supply for their operation. Mechanical energy scavenging mechanisms are viewed and promoted as renewable powering solutions for low-power electronics. However, such energy harvesting mechanisms generate alternating current (AC). Converting AC to DC is a critical issue as it involves using a rectifier, which is not a preferred option considering additional circuitry, power requirements along with the significant threshold voltage of even the most state-of-the-art diodes. DC Triboelectric Nanogenerators (DC-TENG) have emerged as a direct powering solution based on the triboelectric effect, similar to the conventional AC-TENG devices. Such devices incorporate specific strategies like electrostatic breakdown, mechanical switching, and dynamic Schottky junction to generate a unidirectional current. Based on these strategies, different topologies for DC-TENG devices have been developed by researchers over time. Since its inception in 2014, the study on DC-TENG has rapidly emerged and expanded. This article reviews the progress made in association with DC-TENG mechanisms and topologies, theoretical analysis, comparative study, and applications. This article also examines the challenges, recent advancements, and future research prospects in this domain.
