The conversion of diverse polymeric substrates into laser-induced graphene (LIG) has recently emerged as a single-step method for the fabrication of patterned graphene-based wearable electronics with a wide range of applications in sensing, actuation, and energy storage. Laser-induced pyrolysis technology has many advantages over traditional graphene design: eco-friendly, designable patterning, roll-to-roll production, and controllable morphology. In this work, we designed wearable and flexible graphenebased strain and pressure sensors by laminating LIG from a commercial polyimide (PI) film. The as-prepared LIG was transferred onto a thin polydimethylsiloxane (PDMS) sheet, interwoven inside an elastic cotton sports fabric with the fabric glue as a wearable sensor. The single LIG/PDMS layer acts as a strain sensor, and a two-layer perpendicular stacking of LIG/PDMS (x and y laser-directed films) is designed for pressure sensing. This newly designed graphene textile (IGT) sensor performs four functions in volleyball sportswear, including volleyball reception detection, finger touch foul detection during blocking the ball from an opponent player, spike force measurements, and player position monitoring. An inexpensive sensor assists athletes in training and helps the coach formulate competition strategies.

strain sensors have been favored by many researchers for their good flexibility, small size, light weight, and high conformability and have been initially explored for human health monitoring, human-computer interaction, and other fields. [7][8][9][10] The design and development of strain sensing materials are the core of flexible strain sensors. [11][12][13] With the concept of environmental protection and sustainable development deeply rooted, renewable, degradable, and natural fiber materials have become the more competitive materials to manufacture flexible strain sensors due to their low price, easy acquisition, and easy combination with textiles. [14][15][16] Natural fiber materials are mainly divided into cellulose fiber (cotton, fibrilia, and viscose) and protein fiber (wool and silk), which all show excellent softness and can be woven into yarn, nonwoven film, and 2D or 3D fabric with different structural characteristics. [17][18][19][20] The above materials can be directly carbonized or mixed with other conductive nanomaterials to construct flexible conductive networks. These green manufacturing materials have become an important trend to develop flexible strain sensors. [21][22][23] The carbonization temperature and time are the decisive factors for balancing the electrical conductivity and strain sensing performance of carbonized natural fiber materials. [24][25][26] Many studies found that although carbonized fibers exhibit excellent conductivity, they have a small strain range and high brittleness. Thus, they need to be combined with elastic polymers to improve their flexibility and strain capacity. [27][28][29] Original natural fiber materials can maintain excellent softness after they are combined with conductive nanomaterials, but they still exhibit major challenges, such as poor resilience, small strain range, poor wear resistance, and others. Therefore, they need to be combined with elastic polymers to improve the sensing performance. [30][31][32] The main polymer materials are polyurethane (TPU), polydimethylsiloxane (PDMS), and Ecoflex. The breaking elongation of the polymer determines the upper limit of the sensor strain range. The resilience, viscoelasticity, and fatigue resistance of the polymer are very important to the hysteresis, durability, and response speed of the sensor. The interfacial interaction between the polymer and conductive material affects the stability and sensitivity of the sensor. Conductive nanomaterials are diversiform, including carbon black (CB), carbon nanotubes (CNTs), graphene (GR), silver nanoparticles (AgNP), silver nanowires (AgNW), copper nanoparticles Flexible strain sensors with outstanding stretchability and sensitivity can be widely used in medical health, smart robot, intelligent garment, man-machine interaction, and other fields. The use of natural fibers enables a green manufacturing pathway to design strain sensors within the context of increasingly serious environmental pollution. Commercialized natural fibers, including cellulose fibers (cotton and ...

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.
