“…Table 1 showed that the areal specific capacitance, areal energy density and areal power density of CFs@10 wt%-PAN NFs@1 h-PPy yarn-shaped supercapacitors were much better than lately reported yarn-shaped supercapacitors based on PPy [ 13 , 14 , 15 , 29 , 30 , 31 ]. The areal energy density of the CFs@10 wt%-PAN NFs@1 h-PPy yarn-shaped supercapacitors was nearly eight times higher than the supercapacitor based on the electrode of the PPy@CNTs@urethane elastic fiber (6.13 μWh cm −2 ) [ 13 ], about one point five times higher than PPy/SS/cotton (36.2 μWh cm −2 ) [ 14 ], three times higher than PPy/BC [ 15 ], two times higher than PPy/CNT-ionic liquid/AuNP/carbon fiber (24.7 μWh cm −2 ) [ 29 ], five times higher than PPy/MnO 2 /rGO (9.2 μWh cm −2 ) [ 31 ]. This comparison showed that the CFs@10 wt%-PAN NFs@1 h-PPy electrode materials reported in this paper provided a very promising method to produce yarn electrodes for the components of a high-flexibility yarn-shaped supercapacitor.…”

“…For instance, Sun et al fabricate a yarn-shaped supercapacitor based on PPy@CNTs@urethane elastic fiber core spun yarns (UY) which shows an areal specific capacitance of 67 mF cm −2 [ 13 ]. Based on polypyrrole-coated stainless steel/cotton blended yarns, this all-solid-state yarn-shaped supercapacitor presents a great areal specific capacitance of 344 mF cm −2 when the current density is 0.6 mA cm −2 [ 14 ].…”

Yarn-shaped supercapacitors with great flexibility are highly anticipated for smart wearable devices. Herein, a device for continuously producing oriented nanofiber yarn based on solution blowing was invented, which was important for the nanofiber yarn electrode to realize mass production. Further, the yarn-shaped supercapacitor was assembled by the yarn electrode with the polypyrrole (PPy) grown on aligned carbon fiber bundles@Polyacrylonitrile nanofibers (CFs@PAN NFs). Electrical conductivity and mechanical properties of the yarn electrode can be improved by the carbon fiber bundles. The specific surface area of the yarn electrode can be enlarged by PPy. The yarn-shaped supercapacitors assembled by the PVA/LiCl/H3PO4 gel electrolyte showed high areal specific capacitance of 353 mF cm−2 at a current density of 0.1 A g−1, and the energy density was 48 μWh cm−2 when the power density was 247 μW cm−2. The supercapacitors also exhibited terrific cycle stability (82% after 20,000 cycles). We also proved that this yarn-shaped supercapacitor could easily power up the light emitting diode. This yarn-shaped supercapacitor was meaningful for the development of the smart wearable devices, especially when combined with clothing or fabrics.

“…When coating a fiber/filament, researchers are able to create 3D supercapacitor structures from knitted or woven fabric. By utilizing conductive yarns/filaments, the device can exhibit intrinsic flexibility and stretchability. , Singular yarns/filaments can become the cathode, anode, and electrolyte and can be knitted into textile supercapacitors, or they can become twisted and core sheath structures, as seen in Figure . Twisted is when the electrode filaments are wrapped around each other and then coated in the electrolyte so the electrolyte covers and separates them.…”

Smart textiles are transforming the future of wearable technology, and due to that, there has been a great deal of new research looking for alternative energy storage. Supercapacitors offer high discharge rates, flexibility, and long life cycles and can be integrated fully into a textile. Optimization of these new systems includes utilizing electrically conductive materials, employing successful electrostatic charge and/or faradaic responses, and fabricating a textile-based energy storage system without disrupting comfort, washability, and life cycle. This paper examines recent developments in fabrication methods and materials used to create textile supercapacitors and what challenges still remain.

“…Metal wires even allow for soldering or ultrasonic welding at their intersections to establish conductive fiber networks or circuits [39,40]. Finer fibers, typically from stainless steel, show high flexibility [41], but can nevertheless be destroyed by abrasion, especially during washing [42]. One of the ways to overcome this problem is through optimizing the twisting and plying of the yarn [43].…”

Electronic textiles belong to the broader range of smart (or “intelligent”) textiles. Their “smartness” is enabled by embedded or added electronics and allows the sensing of defined parameters of their environment as well as actuating according to these sensor data. For this purpose, different sensors (e.g., temperature, strain, light sensors) and actuators (e.g., LEDs or mechanical actuators) are embedded and connected with a power supply, a data processor, and internal/external communication.
