“…Apart from the mechanical properties needed for the manufacturing process, the textile materials for moisture monitoring have to have certain thermal, electrical and, of course, moisture absorption properties. The latter, also called hygroscopicity, depends on the following factors 26 . Ze presence of hydrophilic functional groups carboxyl (-COOH), sulfonic (-SO 2 OH), hydroxyl (-OH) and amine (-NH 2 ); .…”

“…Absorption takes place until the absorption equilibrium is reached (Table 2), which can take several hours, because the rate of moisture absorption decreases as the equilibrium approaches. 26 Viscose (also referred to as rayon) has high moisture absorption rates and preferable mechanical and textile properties. For textile processing via braiding, the single viscose yarn material offers good tensile strength and good chemical stability.…”

“…The sensor behavior highly correlates with the absorption isotherm of the fiber material according to Bobeth,26 where the relation between the humidity level and the water content is given. As expected, the sensitivity highly depends on the humidity levels, showing a rather low sensitivity in the range of 35-55% RH but a very high sensitivity from 65% RH and above.…”

Novel textile moisture sensors based on multi-layered braiding constructions offer attractive monitoring possibilities for many application fields of e-textiles (electronic textiles), especially for ambient air, which is the main focus of this work. In this paper the theoretical foundations and the production, as well as the procedural, mechanical and humidity tests on newly developed, textile-based sensors for moisture measurement are described. The sensor, which is based on a capacitive measurement principle, was tested in environments ranging from 22% to 94% relative humidity. Within this range, the electrical capacitance of the sensors changed up to 135% of the base capacitance, giving it a very high sensitivity.

“…Between the electrodes of these sensors, a layer of hygroscopic substance serves as a dielectric medium. The material's hygroscopicity is determined by various factors, e.g., hydrophilic functional groups and porosities for water accumulation [29]. Flexible sensors can be integrated into textiles in a variety of ways, including inkjet printing, screen printing, stamp transfer, electrospinning and dip coating or through the inclusion of conductive yarns during the production process [30,31].…”

Silver Conductive Threads-Based Embroidered Electrodes on Textiles as Moisture Sensors for Fluid Detection in Biomedical Applications

Wearable sensors have become part of our daily life for health monitoring. The detection of moisture content is critical for many applications. In the present research, textile-based embroidered sensors were developed that can be integrated with a bandage for wound management purposes. The sensor comprised an interdigitated electrode embroidered on a cotton substrate with silver-tech 150 and HC 12 threads, respectively, that have silver coated continuous filaments and 100% polyamide with silver-plated yarn. The said sensor is a capacitive sensor with some leakage. The change in the dielectric constant of the substrate as a result of moisture affects the value of capacitance and, thus, the admittance of the sensor. The moisture sensor’s operation is verified by measuring its admittance at 1 MHz and the change in moisture level (1–50) µL. It is observed that the sensitivity of both sensors is comparable. The identically fabricated sensors show similar response and sensitivity while wash test shows the stability of sensor after washing. The developed sensor is also able to detect the moisture caused by both artificial sweat and blood serum, which will be of value in developing new sensors tomorrow for smart wound-dressing applications.
