We report a systematic investigation into the optimization of ZnO nanofiber-based NO gas sensors through precise control of structural parameters. By employing electrospinning technique, we fabricated ZnO nanofibers with controlled diameters (160–310 nm) and thicknesses (19–25 μm), enabling detailed analysis of structure–property relationships in g...
Gas sensors based on ZnO nanocomposites have been widely investigated for the detection of various gases. However, few studies have reported electrospun ZnO for NOx gases, especially NO (nitrogen monoxide), due to its high tendency for oxidation upon contact with air. The development of gas sensors that operate at temperatures below 300°C is challe...
Volatile organic compounds (VOCs) have the potential to serve as biomarkers for respiratory diseases such as asthma. Non-invasive respiratory analysis can be used for early detection and disease monitoring. This paper presents the development of a ZnO metal oxide nanofibers sensor as a cost-effective method for detecting NO, which is an asthma biom...
Gas sensors based on nanostructured semiconductor metal oxide (SMO) materials have been extensively investigated as key components due to their advantages over other materials, namely, high sensitivity, stability, affordability, rapid response and simplicity. However, the difficulty of working at high temperatures, response in lower concentration a...
Personal radiative heat regulation using photonic textiles can facilitate a decreased energy consumption in buildings by expanding the range of comfortable ambient conditions. Here, we propose a dual-mode photonic design, which modulates the emissivity using a textured membrane that changes its surface structure between flat and wrinkled. The dual...
This work is part of the European project MOTION (Interreg 2 Seas Mers Zeeën), which aims to develop an exoskeleton for children with cerebral palsy (CP). The developed exoskeleton is equipped with a smart garment in order to detect the stress (e.g. physical, physiological) during the rehabilitation. Five different sensors, i.e. electrocardiogram (...
Nowadays, building insulation must be more and more effective to avoid energy loss. This can result in the lack of ventilation which can cause an increase in the concentration of pollutants in the indoor air, such as Volatile Organic Compounds (VOCs) which are harmful to human health. Different approaches have been proposed to reduce this problem s...
Under dynamic wear conditions, moisture management and heat transfer behaviour of clothing between the human body and its environment are very important attributes for comfort and performance. Especially considering heavy works like firefighting, it is important to analyse liquid moisture management and thermal comfort properties of fabrics that in...
Improving radiative heating performance of textiles is becoming one of the most current research topics to reduce the energy consumption used to control the indoor areas temperature. In this work, the properties of a textile‐based asymmetric design for radiative heating are studied both theoretically and experimentally, and its remarkable efficienc...
The paper deals with the reuse of fibers from textile waste for the development of innovative and sustainable materials applied in the construction field.
Currently, managing the high volumes of textile waste produced, and reducing the damage this waste does to the ecosystem, involves finding solutions for its reuse. Meanwhile, the construction sec...
(1) Background: millions of people, from children to the elderly, suffer from bladder dysfunctions all over the world. Monitoring bladder fullness with appropriate miniaturized textile devices can improve, significantly, their daily life quality, or even cure them. Amongst the existing bladder sensing technologies, bioimpedance spectroscopy seems t...
Smart textiles, incorporating physiological sensors, are paving the way for remote and personalized healthcare. Indeed, their wearable sensors enable continuous and non-invasive monitoring of vital signs, such as an electrocardiogram (ECG), during patients’ daily life without discomfort. Until now, most of the textile electrodes reported are ECG se...
Around 15% of children still wet their bed after five years old. Although bedwetting alarms have proven to be effective to achieve nighttime dryness, they are cumbersome so children could be reluctant to use them. Therefore, the moisture sensor and wire were made unobtrusive by seamlessly integrated them into fully textile underwear by using conduc...
In this study, the loss of the silver content was determined accurately when silver plated nylon electrodes dedicated to a measurement of human physiological parameters are washed with detergents containing bleaching agents. Thermogravimetric analysis and morphological observations based on SEM images have been conducted to determine the quantity o...
Although market prediction for smart textiles in the coming years is high, their washability will be among the main criteria for their mass adoption. Hence, the need to understand precisely how the washing process can damage them. Therefore, the best care instructions can be determined and serve as guidelines for smart textile manufacturers to cont...
The Skin Model is modified with a frame in order to model the microclimate which is present between the skin and the clothing. The aim of the study is to design and instrument the system by allowing dynamic control of moisture management as a function of time. Resistive humidity sensors are placed at 4 locations in the frame to measure the transfer...
The aim of this study is to develop functionalized textile substrates (PES-woven fabric) with TiO2 to photodegrade Volatile Organic Compounds (COVs) in order to improve the Indoor Air Quality (IAQ). As the visible light is more interesting for indoor applications, TiO2 was doped with silver (Ag) and the physical vapour deposition (PVD) was preferre...
We have investigated, theoretically using finite difference time domain method, and experimentally using Fourier transform infrared spectroscopy, the effect of grating's parameters on the reflective properties of ridges and holes' photonic crystal membrane made of polycrystalline silicon in the mid-infrared (MIR) range (5-15 μm). We found that the...
Purpose
Unlike other materials, textiles associate with aesthetic and mechanical properties such as flexibility and removability that allow them to be deployed or folded as required and which make them good candidates for clothing and furnishing but also, eventually, for other applications such as building. Actually, the clothing should ensure app...
In this study, the sorption and desorption isotherms from the dynamic vapor sorption test are modeled by using six different models, that is, the (i) BET (Brunauer–Emmett–Teller), (ii) modified BET, (iii) GAB (Guggenheim–Anderson–Boer), (iv) PEK (parallel exponential kinetics), (v) HH (Hailwood–Horrobin), and (vi) Nelson and Young models. The appli...
Optimal comfort will enable the wearer to work efficiently over long periods of time and help to protect the body from imminent overheating. The thermal performance of fire fighters' protective clothing is primarily based on the thermophysical properties of the materials that are used to construct the clothing. In this study, we have used new fire...
This study presents the development of a textile radiative heat fluxmeter (TRHF) which was designed by weaving technology. The first part of this work focuses on a textile heat fluxmeter (THF) which was developed with the principle of a gradient heat fluxmeter. In order to transform this THF to a TRHF, a polymer with different graphite concentratio...
This study reports on the impact of textile properties on thermal comfort. The fabric weight, thickness, porosity, moisture regain, air permeability and density have been considered and correlated to the thermal and water vapour resistance, permeability index, thermal conductivity and effusivity, and moisture management capacity. Results suggest th...
The impact of thermo-hydric behavior of underwears were studied on comfort. The Pearson method is used to make a correlation between physical and thermo-hydric properties of fabrics. Three parts have been studied, i.e. (i) thermal properties, (ii) hydric properties, and (iii) coupling between thermal and hydric properties. It has been observed that...
The existing heat fluxmeters are rigid and prevent mass transfers since they are nonporous, which results in inaccurate data. By the integration of electroconductor wire (monoconductor or biconductor), a textile heat fluxmeter was developed by a weaving process; through its porous structure this heat fluxmeter allows transfer of moisture. In this s...
This study presents the effect of a woven fabric's material, i.e. polyester (PES), 70/30 polyester/cotton (PES/CO) blend, and its structure, i.e. plain, twill, satin, on the heat and mass transfer properties with regard to development of a textile heat flux sensor. The main purpose of this study is the identification of the most appropriate textile...
