Article Abstract
This study focuses on a novel humidity sensor composed of graphene-oxide (GO)-supported MoTe nanosheets. Conductive Ag electrodes were formed on PET substrates by inkjet printing. A thin film of GO-MoTe was deposited on the Ag electrode used for adsorbing humidity. The experiment's results demonstrate that MoTe are attached to GO nanosheets uniformly and tightly. The capacitive output of the sensors with various ratios of GO/MoTe has been tested for different levels of humidity (11.3-97.3%RH) at room temperature (25 °C). As a consequence, the obtained hybrid film exhibits superior sensitivity (94.12 pF/%RH). The structural integrity and interaction of different components were discussed to afford the prominent humidity sensitivity performance. Under the bending condition, the output curve of the sensor has no obvious fluctuation. This work provides a low-cost way to build flexible humidity sensors with high-performance in environmental monitoring and healthcare.

Wearable sensors integrated with deep learning techniques have the potential to revolutionize seamless human-machine interfaces for real-time health monitoring, clinical diagnosis, and robotic applications. Nevertheless, it remains a critical challenge to simultaneously achieve desirable mechanical and electrical performance along with biocompatibility, adhesion, self-healing, and environmental robustness with excellent sensing metrics. Herein, we report a multifunctional, anti-freezing, self-adhesive, and self-healable organogel pressure sensor composed of cobalt nanoparticle encapsulated nitrogen-doped carbon nanotubes (CoN CNT) embedded in a polyvinyl alcohol-gelatin (PVA/GLE) matrix.

Silk fibroin (SF)-based flexible electronic/photonic materials have gained great attention in wearable devices and soft sensors. However, it remains challenging to understand the molecular interaction mechanisms and subsequently fabricate SF-based flexible materials that exhibit fluorescence, humidity sensitivity, and conductivity properties. In this study, by incorporating lanthanide europium ion (Eu), the design and fabrication of a flexible, fluorescent, and conductive SF membrane was proposed.

Bimorph soft actuators, traditionally composed of two materials with distinct responses to external stimuli, often face durability challenges due to structural incompatibility. Here, we propose an alternative design employing free-standing, isostructural heterogeneous Janus (IHJ) films that harmonize stability with high actuation efficiency. These IHJ films were fabricated through a vacuum self-assembly process, consisting of TiCT MXene nanosheets and hybrid graphene oxide (GO)-biomass bacterial cellulose (BC), with a well-matched two-dimensional lattice structure.

This study presents a systematic analysis of the impact of polymer hole transport layers (HTLs) in inverted MAPbI perovskite solar cells (PSCs). Devices were fully fabricated under regular atmospheric conditions (≈40% humidity) and low temperature (100 °C) by using Field's Metal (FM) as an alternative top electrode. The widely known π-conjugated polymers P3HT, PTB7-Th, PBDB-T, and MEH-PPV were used as HTLs, and all of them show suitable energy alignment to MAPbI, offering good moisture stability, solution processability, low cost, and attractiveness for large area and flexible PSCs.

The development of flexible gas sensors is of growing interest in wearable electronics. However, developing a gas sensor with low operating temperature, high sensitivity, and rapid response remains a huge challenge. Herein, we first develop a polyacrylamide-sodium acrylate-sodium citrate (PAM-Na-SC) hydrogel electrolyte, and design a hydrogel-based nitrogen dioxide (NO) gas sensor enabled by zinc-air batteries (ZABs).
