Abstract:
This paper presents the synthesis of gadolinium aluminate (GdAlO3), an oxide compound with a perovskite structure, for applications as a capacitive and/or resistive humidity sensor. Gadolinium aluminate was synthesized by the sol-gel self-combustion method. This method allowed us to obtain a highly porous structure in which open pores prevail, a structure favorable to humidity sensors. Most of the materials studied as capacitive/resistive humidity sensors have significant sensitivities only with respect to one of these types of sensors. In the case of the studied gadolinium aluminate with p-type electric conductivity, the relative humidity of the air has a significant influence on both capacitive and resistive types of electric humidity sensors. The capacity increases about 10,000 times, and the resistance decreases about 8000 times as the relative humidity increases from 0 to 98%. The investigated gadolinium aluminate can be used successfully to obtain high-sensitivity capacitive and/or resistive humidity sensors.

Abstract:
The growing interest for the environmental monitoring in order to minimize the potential risk of landslide in hillsides and to prevent new disasters, has led the improvement in the development of new materials for manufacturing of capacitive sensor devices more reliable, more versatile and at lower cost. In this sense, ceramics have shown advantages from the point of view of mechanical resistance, resistance to chemical attacks and physical and chemical stability in aggressive environments. In addition, these materials have a unique structure, consisting of grains, grain boundaries, surfaces and pores, the control of which permit the attainment of suitable microstructures to be used as moisture sensors. The goal of this work is to investigate the capability of porous ceramics sensor devices, developed in National Institute of Space Research (INPE), to monitor the soil water dynamics. For that, ceramics sensors microstructures were characterized through scanning electron microscopy (SEM), X-ray diffractometry (XRD) and Hg porosimetry techniques. Electrical measurements were performed in function of water addition in soil samples, up to the saturation limit, for different time intervals, in the same way it happens in area with landslide risk in periods of rain. The analyses of the results evidenced that the ceramics devices are promising ones concerning to their potential in the monitoring of environmental parameters.

Abstract:
In this study, we fabricated a highly flexible fiber-based capacitive humidity sensor using a scalable convergence fiber drawing approach. The sensor’s sensing layer is made of porous polyetherimide (PEI) with its porosity produced in situ during fiber drawing, whereas its electrodes are made of copper wires. The porosity induces capillary condensation starting at a low relative humidity (RH) level (here, 70%), resulting in a significant increase in the response of the sensor at RH levels ranging from 70% to 80%. The proposed humidity sensor shows a good sensitivity of 0.39 pF/% RH in the range of 70%–80% RH, a maximum hysteresis of 9.08% RH at 70% RH, a small temperature dependence, and a good stability over a 48 h period. This work demonstrates the first fiber-based humidity sensor fabricated using convergence fiber drawing.

Abstract:
The amount of water vapours in the air can affect the productivity and safety of many manufacturing processes, such as agriculture, pharmaceuticals, and semiconductor industries, as well as human comfort. The humidity sensors based on porous materials, such as Porous Anodic Alumina (PAA), have persuaded much attention because of their high porosity and tuneable structure. In this work, we have developed a PAA capacitive sensor using phosphoric acid electrolyte by the Differential Pulse Voltammetry method of anodization. The PAA-based humidity sensor shows ultra-high sensitivity, fast response, and a wide detection range of relative humidity (RH). Response and recovery time of the sensor are ~ 16 s and ~ 4 s, respectively at 64 RH%, and the sensor is capable of sensing 1-100 RH%. These results advocate that PAA is a propitious applicant for various humidity sensing applications, especially where low humidity detection is required i.e., paper, lithium-ion battery, tea industries, etc.

Abstract:
PANI coated Cu-ZnS porous microsphere structures have been synthesized by hydrothermal method and in-situ polymerization process. The synthesized composite is characterized by different techniques in order to study the structural, morphological and surface absorption properties. The experimental observation demonstrates that the PANI/1%Cu-ZnS composite has better sensitivity, fast response and good stability as compared to pure PANI and other PANI/CuZnS compositions. Finally, PANI/1% Cu-ZnS composite has been found to be optimized for the humidity sensors due to its well-distributed roughness, porosity and hydrophilicity. The average response and recovery times of the PANI/1% Cu-ZnS are found to be 42 s and 24 s, respectively, which outperform recent results.
