“…19,23 There are challenges associated with the fabrication of Ag/AgCl e-textiles in regards to maintaining conductivity, which is why it is believed that the most recent e-textile fabrication methods focus on highly conductive silver coatings through dipcoating [24][25][26] and electroless plating. 27,28 Also, these fabrication methods generally do not require specialized or expensive equipment. 17 Furthermore, it is important to note that when monitoring biological signals on the surface of the skin, non-polarizable Ag/AgCl electrodes are the current clinical standard due to having low electrode-skin impedance, low noise and minimal motion artifacts, when compared to polarizable electrodes such as those made of stainless steel.…”

The main goal of this work is to develop a fabrication process and system for silver/silver chloride (Ag/AgCl)-coated yarn, as Ag/AgCl is the preferred non-polarizing material for interfacing with the body in a clinical setting when monitoring biological signals. A roll-to-roll electrochemical system was designed and built to deposit AgCl on Ag-coated nylon 6,6 yarn in a controllable process. In particular, the movement of the yarn, voltage limit and mixing of 0.9% sodium chloride solution were held constant while the applied current was varied. The Ag-coated nylon acted as the working electrode with two counter electrodes made of platinum. The optimal Ag/AgCl yarns were then further characterized. The roll-to-roll parameters identified include the applied current of approximately 1.82 mA/cm2 for the Ag-coated nylon yarn with a voltage limit of 2.00 V while in the electrochemical chamber. In addition, the yarn had a uniform movement of 0.08 cm/s, which meant that 7 cm of yarn was in the chamber for approximately 89.17 s. The fabrication process was relatively repeatable, yielding the average resistance of 11.0 ± 1.8 Ω/cm for the optimal Ag/AgCl-coated yarn with a low standard deviation between different fabrication processes. A proof-of-concept system was developed and parameters important for the fabrication of functional Ag/AgCl electronic textiles (e-textiles) were detailed. An effective roll-to-roll fabrication method for Ag/AgCl-coated yarns has the potential to significantly contribute to the design and development of wearable e-textile biological monitoring systems that require Ag/AgCl sensor materials.

“…However, while EPD, DC and DCP methods require sophisticated equipment, by depositing metals in the form of thin films through electrolysis, uniform and continuous textile coatings can be achieved. As such, silver coated conductive and antibacterial cotton fabric were fabricated in Reference [ 10 ], electrical conductive silk fabric also with high antibacterial activity was prepared in Reference [ 11 ], while simple and fast fabrication of conductive silver coatings on carbon fabrics has been reported in Reference [ 12 ]. The obtained hECs have superior mechanical and electrical properties as compared to textiles based on cotton or silk fibers, and this feature makes them suitable in fabrication of photovoltaic devices.…”

We fabricate hybrid magnetoactive materials (hMAMs) based on cotton fibers, silicone oil, carbonyl iron and graphene nanoplatelets (nGr) at various mass concentrations ΦnGr. The obtained materials are used as dielectric materials for manufacturing plane electrical capacitors. The equivalent electrical capacitance Cp and resistance Rp are measured in an electric field of medium frequency f, without and respectively with a magnetic field of magnetic flux density B in the range from 0.1 T up to 0.5 T. The results are used to extract the components ϵr′ and ϵr″ of the complex relative permittivity ϵr*, and to reveal the magnitude of the induced magnetoelectric couplings kx and magnetodielectric effects MDE. It is shown that ϵr′, ϵr″, kx and MDE are significantly influenced by f,B and ΦnGr. We describe the underlying physical mechanisms in the framework of dipolar approximation and using elements of dielectric theory. The tunable magnetoelectric and magnetodielectric properties of hMAMs are useful for manufacturing electrical devices for electromagnetic shielding of living organisms.

“…The most commonly used method is the incorporation of conductive nanomaterials within the nanofibers, such as through assembly, coating, or plating . Among these methods, electroless plating has become an effective method for obtaining thin, homogeneous, conductive coatings because of its simple handling, cost‐effectiveness, and energy savings …”

In this study, we prepared a novel, stretchable, and porous polyolefin elastomer (POE) nanofiber membrane (NM) on the basis of a high-throughput, low-cost, environmentally friendly melt-blending method. To obtain an excellent conductivity, we prepared the Ag-POE composite NM via a facile and effective method of electroless plating. Via the control of the pretreatment process and concentration of the reactant, a homogeneous Ag layer formed on the surface of the POE nanofibers without damaging the original thermal and mechanical properties. Because of the good stretchability, conductivity, and porosity, the Ag-POE NM was used as a strain sensor to detect the pressure and airflow. When the silver nitrate concentration was 4 g/L, a good sensitivity and durability were obtained. The current change accurately recorded the deformation of the membrane under different pressures and air flows. The results of this study provide us with an industrial method to prepare Ag-POE NM and indicate its potential application as a strain sensor for outer stimuli detection.
