abstract = {Abstract Fabric-based energy storage devices are essential for next-generation wearable electronics, requiring materials that combine lightweight structure, high conductivity, and mechanical durability. Laser-induced graphene (LIG) is a promising candidate due to its tunable surface chemistry, excellent electrical properties, and compatibility with textile substrates. However, improving its electrochemical performance often involves chemical modifications with metal oxides or polymers, complicating processing and limiting scalability. Traditional synthesis methods for oxygen-rich graphene rely on hazardous chemicals and labor-intensive procedures. In this work, we present an eco-friendly, one-step laser-scribing technique to fabricate oxygen-functionalized LIG directly on Kevlar textiles, enabling the creation of flexible, fabric-based energy storage devices without the need for chemical treatments. By carefully controlling the laser power (P) and scan speed (S), we achieve a precise balance between graphitization and oxygen functionalization. Density functional theory analysis reveals that specific oxygen groups—carboxyl, hydroxyl, epoxy, and carbonyl—play a key role in enhancing potassium-ion adsorption. The optimized LIG-P3S1 sample (laser power level 3, scan speed level 1) exhibits a high carbon content of 89.12 At%, with 67.51% of oxygen groups from C–O and C–OH bonds. This surface chemistry results in an areal capacitance of 88.92 mF cm−2 at 0.3 mA cm−2, along with good cycling stability, retaining 66.67% capacitance after 10 000 cycles. The device also demonstrates stable performance under bending angles of up to 120°, making it suitable for wearable applications. This work offers a scalable, sustainable approach to flexible energy storage, with potential applications in wearable and biomedical electronics.},

abstract = {The vast availability of ambient mechanical vibrations in the natural environments and our daily activities has spurred the advancement of triboelectric sensors for vibration sensing. However, the operation of the traditional triboelectric vibration sensors (VSs) is usually constrained to contact–separation mode, limiting their functionality to transverse vibrations and making them unsuitable for longitudinal and rotary movements. The inherent wear and tear associated with the contact–separation mode further restricts their practical application. To address these limitations, this study presents a new design for a VS that employs a spring-assisted inverted pendulum structure. The VS exhibits a 10 Hz resonant frequency and produces maximum triboelectric output at the vibration amplitude of 5 mm. As a proof of concept, the VS successfully detects balanced and unbalanced fan blades by analyzing the obtained data via fast Fourier transform analysis. Besides machine monitoring, the proposed VS can be integrated into a wearable device for tracking human wrist movements. Combined with a machine learning algorithm, the sensor has achieved an accuracy level of greater than 95% in recognizing four distinct wrist motions: bending, rotating, waving, and handshaking. These findings have proven that the proposed triboelectric sensor design can be effectively integrated into wearable technologies, smart factories, and virtual/augmented reality systems, significantly broadening the triboelectric sensor applications.},

abstract = {Amid the increasing demand for advanced gas sensing technologies, particularly for ammonia gas detection, this study presents an innovative solution for far-field sensing at room temperature. Widely used in various industrial applications, ammonia poses significant environmental and health risks, emphasizing the need for efficient monitoring. Although traditional gas sensing methods effective, they often constrained by high operating temperatures and complex electronic components, limiting their practicality. In response, transparent thin films have emerged as a promising alternative, offering real-time monitoring capabilities. However, existing transparent films often rely on external stimuli for activation, resulting in higher power consumption and degradation over time. This research investigates a transparent thin film composed of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) incorporated with graphene nanoplatelets (GNPs) for far-field ammonia gas sensing. Synthesized through a low-temperature, full-solution approach, the film demonstrates an average transmittance of 76.18 % in visible spectrum. Notably, patterning this film into a single slot antenna exhibits a significant 60 MHz frequency shift at a far-field distance of 12 cm when exposed to 50 ppm of ammonia gas. This significant frequency shift underscores the potential of the developed transparent slot antenna for practical and unobtrusive far-field sensing, advancing transparent gas sensors applications in environmental monitoring and workplace safety.},

The synthesized GO and reduced graphene oxide (rGO) were evaluated using UV-visible spectroscopy, FT-IR spectroscopy, XRD, SEM, and EDX. The findings showed that processing graphite powder with KMnO4 at 60 °C for 12 hours resulted in a high degree of oxidation and minimal defects. Furthermore, ascorbic acid, an alternative to highly toxic hydrazine, aided in eliminating oxygen-containing functional groups in the rGO. This study focuses on the properties of GO produced using the improved Hummer's method, and the changes observed after chemical reduction.</jats:p>},

abstract = {The integration of flexible sensors into human–machine interfaces (HMIs) is in increasing demand for intuitive and effective manipulation. Traditional glove-based HMIs, constrained by nonconformal rigid structures or the need for bulky batteries, face limitations in continuous operation. Addressing this, we introduce yarn-based bend sensors in our smart glove, which are wirelessly powered and harvest energy from a fully textile 5.8 GHz WiFi-band antenna receiver. These sensors exhibit a gauge factor (GF) of 5.60 for strains ranging from 0 to 10%. They show a consistent performance regardless of the straining frequency when being stretched and released at frequencies between 0.1 and 0.7 Hz. This reliability ensures that the sensor output is solely dependent on the yarn’s elongation. Accurately detecting finger-bending movements from 0° to 90° in a virtual environment, the sensors enable enhanced degrees of freedom for human finger interaction. When integrated with advanced machine-learning techniques, the system achieves a classification accuracy of 98.75% for object recognition, demonstrating its potential for precise and accurate HMI. Unlike conventional near-field energy transfer methods that rely on magnetic flux and are limited by power loss over distance, our fully textile design effectively harvests microwave energy, showing no voltage deterioration up to 1 m away. This minimalist microwave-powered smart glove represents a significant advancement, offering a viable and practical solution for developing intuitive and reliable HMIs.},

Monitoring liquid fertilizer concentration is crucial to increase crop yields. However, most of the proposed monitoring systems lack integration with Internet of Things (IoT) technology. This study proposes a planar microwave sensor enhanced with IoT technology for real-time cloud monitoring of urea concentration. The proposed microwave sensor offers the advantages of fast response time, non-intrusive, and non-invasive. The microwave sensor is designed using CST Microwave Studio. The measured transmission coefficient (S21) sensitivity of the microwave sensor for urea is 3.20 dB/(g/mL) at 2.37 GHz, showing that the microwave sensor is sensitive to the change in urea concentration. The portable liquid fertilizer concentration measurement system is developed where the microwave sensor can be used without the need for a bulky instrument. The measurement system also shows great accuracy as the predicted concentrations have the high R2 and low RMSE of 0.9689 and 0.0433, respectively, with the actual concentration. An IoT-enabled Wi-Fi connection is established where the liquid fertilizer concentration data can be conveniently monitored in real time.},

With the application of the two tuning mechanisms, the tag resonant frequency can be easily tuned by adjusting the geometrical parameters of the truncations and the I-slit, without the involvement of metallic vias/stubs and multiple-layer structures.
