“…E-textiles combine electrical conductivity with flexibility, stretchability, wearability, wrapping large surface area for sensing, and making them an ideal for wearable electronics applications where the traditional rigid electronics are lacking. E-textiles cover a broad area of applications including thermal therapy [1], wearable energy harvesting/storage [2][3][4], real-time healthcare monitoring [5], electromagnetic interference shielding [6], and other flexible and portable wearable electronics applications [7,8]. Conductive textiles are the most integral parts of e-textiles.…”

“…Conductive textiles are the most integral parts of e-textiles. Conductive textiles have been produced by several approaches including electroless metal deposition [9], inserting metal wires in the fabric [2], using intrinsically conductive fibers and yarns [10], coating with conductive polymers [11][12][13], in situ polymerization of conductive polymers on the fabrics [14,15], and pyrolysis of the textile [16].…”

Conductive elastic fabrics are desirable in wearable electronics and related applications. Highly elastic conductive polyamide/lycra knitted fabric was prepared using intrinsically conductive polymer poly (3,4-ethylenedioxythiophene) (PEDOT) blended with polyelectrolyte poly (styrene sulfonate) (PSS) using easily scalable coating and immersion methods. The effects of these two methods of treatments on uniformity, electromechanical property, stretchability, and durability were investigated. Different grades of waterborne polyurethanes (PU) were employed in different concentrations to improve the coating and adhesion of the PEDOT:PSS on the fabric. The immersion method gave better uniform treatment, high conductivity, and durability against stretching and cyclic tension than the coating process. The surface resistance increased from * 1.7 and * 6.4 X/square at 0% PU to * 3.7 and * 12.6 X/square at 50% PU for immersion and coating methods, respectively. The treatment methods as well as the acidic PEDOT:PSS did not affect the mechanical properties of the fabric and the fabric showed high strain at break of * 650% and remained conductive until break. Finally, to assess the practical applicability of the treated fabric for wearable e-textiles, the change in surface resistance was assessed by cyclically stretching 10 times at 100% strain and washing in a domestic laundry for 10 cycles. The resistance increased only by a small amount when samples were stretched cyclically at 100% strain, and the samples showed good durability against washing.Melkie Getnet Tadesse and Desalegn Alemu Mengistie have contributed equally to this work.

“…The demand for small smart devices in modern, fast-developing technologies requires materials that can be adapted on flexible substrates for applications such as flexible electrodes in batteries [1], super capacitors [2] and other energy storage devices [3,4], flexible solar cells [5], micro-actuators [6], and sensors [7,8]. Conducting polymers may be suitable for those devices, but their formation as simple, chemically-deposited coatings leads to certain limitations of the materials chosen; furthermore, their performance is reduced in comparison to electrochemically-polymerized conducting polymers.…”

Combining ink-jet printing and one of the most stable electroactive materials, PEDOT:PSS (poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)), is envisaged to pave the way for the mass production of soft electroactive materials. Despite its being a well-known electroactive material, widespread application of PEDOT:PSS also requires good understanding of its response. However, agreement on the interpretation of the material’s activities, notably regarding actuation, is not unanimous. Our goal in this work is to study the behavior of trilayers with PEDOT:PSS electrodes printed on either side of a semi-interpenetrated polymer network membrane in propylene carbonate solutions of three different electrolytes, and to compare their electroactive, actuation, and energy storage behavior. The balance of apparent faradaic and non-faradaic processes in each case is discussed. The results show that the primarily cation-dominated response of the trilayers in the three electrolytes is actually remarkably different, with some rather uncommon outcomes. The different balance of the apparent charging mechanisms makes it possible to clearly select one electrolyte for potential actuation and another for energy storage application scenarios.

noninvasive applications such as sweat sensing. [18] To this end, we develop a novel ion-selective microelectrode array platform with high spatial resolution. We fabricate the platform using photolithography for patterning electronic wiring and insulation, electrodeposition for surface modification, and ISMs through an advanced process involving temporary polydimethylsiloxane (PDMS) microfluidic channels. As a proof of concept, we apply this device to detect the ion concentration change in culture medium. [36,37] Figure 1 comprises schematic views and the working mechanism for this device. Figure 1a describes the schematic view of the device with multiple ion sensors, including the K + -sensor, Na + -sensor, and Cl − -sensor. The inner electrode for each ion is 500 µm × 500 µm, and the space between two electrodes is 400 µm. With multiple ion sensors, the device enables to simultaneously monitor [K + ], [Na + ], and [Cl − ] in electrolyte solutions. We fabricate the sensor array on a silicon wafer with a process that combines photolithography for connectors, electrochemical deposition for electrodes, and microfluidics for ISM patterning ( Figure S1, Supporting Information). Figure 1b illustrates the working principle of the sensor array. When the device is placed in an electrolyte solution (e.g., KCl, NaCl, and KNO 3 ), the target ion will diffuse across a polymer membrane that is made selective with the addition of an ionophore. Diffusion continues until the concentration of the target ion is in equilibrium between the outside of the membrane in contact with the electrolyte solution and the inside of the membrane in contact with the electrode. The concentration of the target ion on the electrode surface affects the electrode potential and the corresponding ionic concentration can be can be calculated from the electrode voltage using Nernst equation. Figure 2 displays a microfluidic-based method for the PVCbased polymer membrane patterning on a substrate that already includes Au wires. A parylene thin film coated on top acts as the encapsulation layer and creates windows for electrode electrodeposition (Figure 2a). For electrodes, we use poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) to create electrodes with high capacitance. [38,39] As shown in Figure 2b, we deposit PEDOT:PSS from electrochemical polymerization of a solution containing 0.01 m EDOT and 0.1 m NaPSS. [38][39][40] The PEDOT:PSS coated electrodes have higher capacitance than the bare Pt electrodes ( Figure S2, Supporting Information), which is important for sensor performance. To selectively pattern the ISMs, we use a PDMS mold as template (Figure 2c,g). We then position the mold onto the substrate, align it to the electrodes, A balanced concentration of ions is essential for biological processes to occur. For example, [H + ] gradients power adenosine triphosphate synthesis, dynamic changes in [K + ] and [Na + ] create action potentials in neuronal communication, and [Cl − ] contributes to maintaining appropriate cell membrane...
