Summary: This study developed an accurate and reliable quartz crystal microbalance (QCM) humidity sensor based on the chitosan-halloysite nanotubes (CS-HNTs) composite for monitoring respiration lines. The CS-HNTs film showed high sensitivity (69.1 Hz/% RH), superior humidity hysteresis (<2.8% RH), excellent long-term stability, repeatability, and outstanding selectivity. The QCM humidity sensor could detect subtle changes in fingertip movements and exhaled air humidity in different modes. A respiratory behavior monitoring model based on support vector machines accurately determined five breathing modes for human breath detection and health medical diagnosis.

Summary: In this study, Ho2O3/GO composites were obtained by ultrasonic stirring of the GO solution with the synthesized Ho2O3 material. The humidity response of Ho2O3/GO sensor has nearly doubled from 1102 to 2136, and the recovery time was reduced by more than half from 6 s to 1 s, benefiting from the presence of adsorbed hydroxyl oxygen and the regular arrangement of the nanosheets. The sensor was used for non-contact scanning to identify water zones of different shapes, presenting information on the distribution of water beneath the sensor. This research opens up further possibilities for the expansion of humidity sensors in emerging applications such as smart sensing.

Summary: The study synthesizes a large number of MoS2 flakes using sodium molybdate as the precursor, which is larger than those produced by other CVD methods. Humidity sensors based on MoS2 are developed using this method, exhibiting a response-switching phenomenon under high humidity conditions due to the presence of Na2MoO4 residues. By decreasing the concentration of the precursor and using a post-fabrication surface treatment, the response-switching effect can be eliminated.

Summary: Polymers and polymer composites are ideal for wearable and flexible humidity sensors due to their flexibility, low cost, and ease of processing. However, their long-term stability is a concern. In this study, chemically crosslinked TA-x-PEI based humidity sensors were fabricated through a simple spray coating process using the robust Michael addition reaction between PEI and TA. The combination of TA-x-PEI with PC-IDE allowed for the fabrication of high-performance flexible humidity sensors with fast response and recovery, low hysteresis, good long-term stability, and high sensitivity.

Summary: A sensitive H2S sensor for detecting low concentrations of H2S in SF6 electrical equipment was developed using ZnO nanorods-modified SnS2 Debye nanowires. At an optimum temperature of 180 degrees C, the sensor showed a response time of 10 s and a recovery time of 51 s to 30 ppm H2S, with a response value of 71.2%. The sensor exhibited a detection limit as low as 50 ppb for H2S, along with excellent stability, moisture resistance, and long-term stability. The study also demonstrated that ZnO enhanced the adsorption performance of SnS2 on H2S. The H2S sensor prepared using ZnO-SnS2 is expected to be a promising candidate for detecting hazardous gases in the environment and SF6 decomposition products.

Summary: 3D printing inks based on rGO/Fe3O4@Polyacrylonitrile nanosheets were studied as high-performance organic semiconductors. The chemical structures of the nanosheet components were characterized using spectroscopic techniques, and their thermal stability, crystal structure, and surface topology were investigated. Two different methods for forming the nanocomposites, annealing and microwave-assisted methods, were thoroughly studied. The microwave-assisted method showed higher stabilization and better electrical properties, making it suitable for use in organic semiconductor technology. The short gelation time of the microwave-assisted nanocomposite also makes it a promising ink for 3D printing of flexible electronic chips.

Summary: The unique electrical properties and chemical modifiability of fullerenes make them suitable for the fabrication of various measurement devices. In this study, a fullerene derivative called C60-Lys, modified with -OH, -NH2, and -COONa groups, has been creatively used to develop a humidity sensor with high response (>2000) and low hysteresis (<2.9% RH). The sensor shows excellent reproducibility and stability, with a response time of 24s and recovery time of 29s in the range of 11-97% relative humidity (RH). The adsorption and desorption of water molecules on the sensor surface are attributed to hydrogen bonding, van der Waals forces, and ion formation.

Summary: Immediate research is needed to investigate the poor performance of monolayer carbon atom (rGO) composites as humidity sensors. In this study, a (x)rGo+(1-x)CoCr2O4(x = 0,0.1,0.2 and 0.3) composite was tested as a humidity sensor. The method used was simple, cost-effective, and suitable for mass production. The research aimed to determine if the (x)rGo+(1-x)CoCr2O4 composite could enhance the responsiveness of humidity sensors at room temperature. X-ray diffraction (XRD) was used to analyze the crystallinity, phase, and structure of the composite. The results showed that the compound had a high sensing response at a concentration of x = 0.3.

Summary: Fast detection of low-concentration H2S gas is crucial for the proper functioning of SF6 electrical insulation equipment. A sensor made of LaF3 quantum dot modified SnS2 nanorods was developed for H2S gas detection, which exhibited excellent stability, moisture resistance, selectivity, and long-term stability at an optimal operating temperature of 150°C. The sensor showed a response value of 85.2% to 30 ppm H2S, with response and recovery times of 4 s and 93 s, respectively. The enhanced performance of the sensor can be attributed to the synergistic effect and heterojunction effect of the LaF3 quantum dots.

Summary: The evaluation of indoor humidity is challenging compared to other environmental parameters. High-performance humidity sensors can be achieved by selecting appropriate sensing materials and structural tuning. In this study, SnO2/rGO and SnO2/rGO doped with Co nanocomposites were produced and characterized. The incorporation of Co onto the rGO/SnO2 composite was confirmed by XRD, SEM, and TEM analysis. The humidity sensing behavior of both structures was evaluated, and the results showed that Co doping improved the sensitivity, response time, and recovery time.

The sensor's hydrophilic groups and porous structure contributed to its enhanced humidity sensitivity. The GG/EC-PVP sensor could capture and measure typical breathing patterns in different human emotions, and could also be used for lie detection.
