In this work, we propose a humidity sensor based on methyl green thin film. A surface-type humidity sensor Al/MG/Al was fabricated by depositing methyl green thin film between aluminum electrodes. The structural, optical and surface morphological properties of the thin film were characterized by XRD, UV Vis and FESEM. The sensing properties with high sensitivity as well as response time 200 s and recovery 60 s of the humidity sensor were investigated by measuring the capacitance and resistance at 1, 10 and 100 kHz with the humidity varying range from 32 to 85% RH. These measured values were analyzed by classical statistics and neutrosophic statistics. As a result, it was observed that neutrosophic statistics were more informative, flexible and adequate than classical statistics for analyzing the measured values of capacitance and resistance.

Achieving high flexibility, breathability, and sensitivity in inorganic semiconductor gas sensors remains a substantial challenge, especially for wearable applications in high-humidity environments. This study develops a hyper-flexible, thermally stable, and highly breathable full-inorganic, self-supporting InGaO-AlO/AlO nanofiber membrane sensor, fabricated using a dual-spinneret electrospinning method with an interlocking design. This innovative sensor has a bilayer structure with an amorphous AlO nanofiber substrate layer supporting an active layer of high-aspect-ratio interwoven InGaO and AlO nanofibers, providing outstanding flexibility, elevated breathability, and strong thermal stability.

Since their discovery, titanium-based MXenes (TiCT) have attracted significant attention. Several studies have presented versatile, cost-effective, and scalable approaches for fabricating TiCT-based functional components. However, most previous studies only allowed the realization of 2D patterns or required diverse additives to produce 3D architectures.

Borophene, a two-dimensional allotrope of boron, has emerged as a promising material for gas sensing because of its exceptional electronic properties and high surface reactivity. This review comprehensively overviews borophene synthesis methods, properties, and sensing applications. However, it is crucial to acknowledge the substantial gap between the abundance of theoretical literature and the limited experimental studies.

As one of the core parts of the Internet-of-things (IOTs), multimodal sensors have exhibited great advantages in fields such as human-machine interaction, electronic skin, and environmental monitoring. However, current multimodal sensors substantially introduce a bloated equipment architecture and a complicated decoupling mechanism. In this work we propose a multimodal fusion sensing platform based on a power-dependent piecewise linear decoupling mechanism, allowing four parameters to be perceived and decoded from the passive wireless single component, which greatly broadens the configurable freedom of a sensor in the IOT.

This paper focuses on a four-capacitor flexible sensor composed of two electrode materials; also, the decoupling method and sensing performance for multimodal sensing of spatial forces and dynamic humidity are described. In previous work, decoupling of multimode sensors is mostly done by monitoring the types of signals, numerical differences of the same signal, and stacking multiple parameter-sensitive materials. This paper mainly uses the different characteristics of the two electrode materials; in the simulation and experiment of humidity, the moisture-sensitive electrode quickly wets from the outside to the inside and expands, and the contact angle quickly decreases from 58.
