“…In addition, other parameters, such as the influence of technology, etchant type, and substrates also hold a vital role in determining the efficiency and controllability of thinning. Proper optimization of these parameters is essential for achieving high-quality, ultrathin 2D materials, [94][95][96][97][98] enabling their integration into next-generation nanoelectronic and optoelectronic devices.

“…After that, the dispersed suspension was processed for centrifugation at 5000 rpm for 30 min. Upon discarding the supernatant, the residue was washed with DMF several times to eliminate any unreacted or precursor component [29]. After purification, the residue was dispersed in DMF and was kept for further study.…”

Here we report the liquid–solid interaction in droplet-based triboelectric nanogenerators (TENG) for estimation of human Na+/K+ levels. The exploitation of PVDF-HFP encapsulated WS2 as active layer in the droplet-based TENG (DTENG) leads to the generation of electrical signal during the impact of water droplet. Comparison over the control devices indicates that surface quality and dielectric nature of the PVDF-HFP/WS2 composite largely dictates the performance of the DTENG. The demonstration of excellent sensitivity of the DTENG towards water quality indicates its promising application towards water testing. In addition, the alteration in output signal with slightest variation in ionic concentration (Na+ or K+) in water has been witnessed and is interpreted with charge transfer and ion transfer processes during liquid–solid interaction. The study reveals that the ion mobility largely affects the ion adsorption process on the active layer of PVDF-HFP/WS2 and thus generates distinct output profiles for diverse ions like Na+ and K+. Following that, the DTENG characteristics have been exploited to artificial urine where the varying output signals have been recorded for variation in urinary Na+ ion concentration. Therefore, the deployment of PVDF-HFP/WS2 in DTENG holds promising application towards the analyse of ionic characteristics of body fluids.

“…In addition to MoS 2 , various other 2D materials have been studied. In one study, [ 471 ] a group of researchers investigated four different kind of 2D TMDCs: WS 2 , MoS 2 , WSe 2 , and MoSe 2 . Surprisingly, they observed that WSe 2 had the greatest output voltage, reaching up to 286 V, outperforming the other materials.…”

Wearable electronic textiles (e‐textiles) have emerged as a transformative technology revolutionizing healthcare monitoring and communication by seamlessly integrating with the human body. However, their practical application has been limited by the lack of compatible and sustainable power sources. Various energy sources, including solar, thermal, mechanical, and wind, have been explored for harvesting, leading to diverse energy harvesting technologies, such as photovoltaic, thermoelectric, piezoelectric, and triboelectric systems. Notably, 2D materials have gained significant attention as attractive candidates for energy harvesting and storage in e‐textiles due to their unique properties, such as high surface‐to‐volume ratio, mechanical strength, and electrical conductivity. Textile‐based energy harvesters employing 2D materials offer promising solutions for powering next‐generation smart and wearable devices integrated into clothing. This comprehensive review explores the utilization of 2D materials in textile‐based energy harvesters, covering their preparation, fabrication, and characterization strategies. Recent advancements are highlighted, focusing on the integration of 2D materials and their practical implementations, shedding light on the performance and effectiveness of 2D‐material‐based energy harvesters in e‐textiles, and highlighting their potential as a sustainable alternative to conventional power supplies in wearable technologies.
