Article Abstract
In light of the crucial role of marine ecosystems and the escalating environmental conservation challenges, it is essential to conduct marine monitoring to help implement targeted environmental protection measures efficiently. Energy harvesting technologies, particularly triboelectric nanogenerators (TENGs), have great potential for prolonging the lifespan and enhancing the reliability of sensors in remote areas. However, the high internal resistance, low current, and friction-induced abrasion issues of TENGs limit their performance in practical applications. This work presents a rolling mode triboelectric nanogenerator that utilizes multi-tunnel grating electrodes and the opposite-charge-enhancement mechanism to harvest wave energy efficiently. The device achieves significant instantaneous and root mean square power density of 185.4 W/(m·Hz) and 10.92 W/(m·Hz), respectively. By utilizing stacked devices and an exclusively designed power management module, a self-powered ocean sensing system including computing and long-range wireless communication (0.8 km) capabilities was developed. Laboratory and in-situ ocean tests were conducted to assess and validate the system. This work offers a potential solution for the challenging deployment of marine self-powered sensing nodes.

Gel-based electronic skin (e-skin) has recently emerged as one of the most promising interfaces for human-machine interaction and wearable devices, owing to its exceptional flexibility, extensibility, transparency, biocompatibility, high-quality physiological signal monitoring, and system integration suitability. However, conventional hydrogel-based e-skins may exhibit limitations in mechanical strength and stretchability compatibility, as well as poor environmental stability. To address these challenges, following a top-down fabrication strategy, this study innovatively integrates poly(methacrylic acid), titanium sulfate, and ethylene glycol (EG) into the three-dimensional collagen fiber network structure of zeolite-tanned sheepskin to successfully develop an organogel (SMEMT) e-skin, which exhibits superior high toughness, environmental stability, high transparency (74% light transmittance at 550 nm), antibacterial properties and ecological compatibility.

In this study, porous polysiloxane (PS)/multi-walled carbon nanotube (MWCNT) nanocomposite films were developed as high-performance triboelectric layers for flexible triboelectric nanogenerators (TENGs). TENGs convert mechanical motion into electricity and offer a promising solution for self-powered electronic systems. The nanocomposites were fabricated using a doctor blading method, and porosity was introduced a simple, scalable salt-leaching technique.

Molybdenum disulfide (MoS) has recently emerged as a promising material for the development of triboelectric nanogenerators (TENGs) owing to its inherently negative triboelectric properties when paired with polymeric layers, along with its notable transparency and mechanical flexibility. However, MoS-based TENGs operating in the contact-separation mode encounter critical limitations, including mechanical wear and limited triboelectric performance, particularly within the constraints of conventional 2D geometries. This paper reports the novel one-step laser-assisted synthesis of hemispherical MoS through the controlled nucleation and growth of MoS precursor seeds.

Cellulose-based triboelectric nanogenerators (TENGs) have garnered significant attention in wearable electronics due to their biodegradability and abundant availability. However, the near-electroneutrality of cellulose hinders its advancement and broader application in high-performance TENGs. In this study, the triboelectric polarity of cellulose nanofibers (CNF) is modified by grafting different functional groups, wherein the incorporation of polar sulfonic acid groups enhances the deep trap density on the surface of CNF by an order of magnitude, reduces charge dissipation rates, and increases surface potential by nearly 200 % compared to untreated CNF.

This study presents a novel photovoltaic triboelectric nanogenerator (PTENG) that operates on sliding contacts between n-type (gallium arsenide) GaAs and metal electrodes in the presence of periodic light illumination, which offers harvesting energy synergistically by integrating both photovoltaic and triboelectric effects to enhance the energy output. Using an in-house built test setup with provision of laser illumination, the open-circuit voltage () and short-circuit current () were measured for the n-GaAs semiconductors with different metal contacts (Al and Cu). Under both laser light (630 nm) and without laser light conditions, n-GaAs with aluminum contacts exhibited the highest and values, reaching up to 11.
