“…Based on the optimization of materials, several other advanced designs have also been reported to demonstrate that the elastic structure is effective in improving the durability of the TENG. [128][129][130][131][132][133][134][135] Non-Contact Structure: Up to now, TENG has proven to be an effective technique for converting low-frequency mechanical energy into electric energy through the coupling of triboelectrification and electrostatic induction. It is worth noting that due to the electret characteristics of the triboelectric material, the triboelectric charge of the S-TENG can remain on the material surface after the initial triboelectrification.…”

With rapid development of the Internet of Things (IoTs) era, a variety of miniaturized and distributed electronics appear in every corner of industrial production and daily life. The shortage of fossil fuels requires renewable clean energy to replace traditional energy to meet the needs of smart and low‐power devices. Triboelectric nanogenerator (TENG) is a new technology for converting high‐entropy mechanical energy into electric energy to power these devices. However, improving the output energy and durability of TENG remains a considerable challenge for practical applications. To solve these problems and push forward its commercialization process, this paper systematically reviews how to improve the durability of the sliding mode TENG (S‐TENG) from the aspects of material optimization and structural design. Besides, a variety of ways are introduced to improve the electric output of the S‐TENG under the premise of high durability. At last, challenges and future research focus in this field are also predicted, which provide a guideline for the research of the high electric output and ultra‐durability TENG for highly efficient energy harvesting and self‐powered sensing applications in the IoTs.

“…By optimizing the polarization, dimensions, and the number of segments of the triboelectric layer, an instantaneous power density of 0.32 mW cm −2 is generated. Wang et al [28] developed a combination of AC and DC generation units within a single device. The DC current is generated through the contact of the rotator with two conductive rods, while an AC output is generated by sliding motion between a pair of rotating layers.…”

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.

Triboelectric potential gated transistors have inspired various applications toward mechanical behavior controlled logic circuits, multifunctional sensors, artificial sensory neurons, etc. Their rapid development urgently calls for high-performance devices and corresponding figure of merits to standardize the tribotronic gating properties. Organic semiconductors paired with solution processability promise low-cost manufacture of high-performance tribotronic transistor devices/arrays. Here, we demonstrate a record high-performance tribotronic transistor array composed of an integrated triboelectric nanogenerator (TENG) and a large-area device array of C8-BTBT-PS transistors. The working mechanism of effective triboelectric potential gating is elaborately explained from the aspect of conjugated energy bands of the contact-electrification mediums and organic semiconductors. Driven by the triboelectric potential, the tribotronic transistor shows superior properties of record high current on/off ratios (>108), a steep subthreshold swing (29.89 μm/dec), high stability, and excellent reproducibility. Moreover, tribotronic logic devices modulated by mechanical displacement have also been demonstrated with good stability and a high gain of 1260 V/mm. The demonstrated large-area tribotronic transistor array of organic semiconductor exhibits record high performance and offers an effective R&D platform for mechano-driven electronic terminals, interactive intelligent system, artificial robotic skin, etc.
