“…Rapid breakthrough in improving the conductivity through silver ion diffusion into the fluidic graphene oxide fiber during wet spinning coagulation process. The as-designed sensor possesses greater sensitivity and works up to 20% strain [222]. Although the conductivity and sensing range have been progressing, the recovery ratio for the wet-spun fibers remains at a lower strain%, and Gao et al framed the strategy of forming tri-composite (PEDOT:PSS/PVA/ethylene glycol) sensors, showing a promising recovery up to 20% strain [223].…”

The Conducting of polymers belongs to the class of polymers exhibiting excellence in electrical performances because of their intrinsic delocalized π- electrons and their tunability ranges from semi-conductive to metallic conductive regime. Conducting polymers and their composites serve greater functionality in the application of strain and pressure sensors, especially in yielding a better figure of merits, such as improved sensitivity, sensing range, durability, and mechanical robustness. The electrospinning process allows the formation of micro to nano-dimensional fibers with solution-processing attributes and offers an exciting aspect ratio by forming ultra-long fibrous structures. This review comprehensively covers the fundamentals of conducting polymers, sensor fabrication, working modes, and recent trends in achieving the sensitivity, wide-sensing range, reduced hysteresis, and durability of thin film, porous, and nanofibrous sensors. Furthermore, nanofiber and textile-based sensory device importance and its growth towards futuristic wearable electronics in a technological era was systematically reviewed to overcome the existing challenges.
