Over recent years, thermoplastic polyurethane (TPU) has been widely used as a substrate material for flexible strain sensors due to its remarkable mechanical flexibility and the ease of combining various conductive materials by electrospinning. Many research advances have made in preparation with better ductility, higher sensitivity, wider sensing range using TPU combination through However, there is lack reviews that provide systematic comprehensive summary outlook this area. In review paper, working principles electrospinning technology are initially described. Subsequently, based on electrospun tracked discussed, focus incorporation fillers such carbonaceous materials, MXene, metallic polymers. Moreover, wide applications thoroughly discussed. Finally, future prospects challenges fields pointed out.

Soft and stretchable strain sensors have found wide applications in health monitoring, motion tracking, robotic sensing. There is a growing demand for amphibious environments, such as implantable sensors, wearable swimmers/divers, underwater sensors. However, developing sensitive, stretchable, robust sensor remains challenging. This work presents an encapsulated sensor. The conductive layer, made of silver nanowires embedded below the surface polydimethylsiloxane, was sandwiched by two layers thermoplastic polyurethane. Periodic sharp cuts were introduced to change direction flow from across along path defined opening cracks. crack advancing controlled unique combination weak/strong interfaces within sandwich structure. cut design interfacial interactions between investigated. exhibited high gauge factor up 289, linear sensing response, fast response time (53 ms), excellent robustness against over-strain, stability after 16 000 loading cycles 20 days aqueous saline solution. functionality this demonstrated tracking fish, undertaking language recognition underwater, monitoring blood pressure porcine aorta. illustrates promising potential both use surgically applications.

Flexible strain sensor-based smart textiles have promising applications in wearable devices. However, most existing suffer from complex fabrication processes and inadequate control over the patterning uniform deposition of conductive materials, which significantly hinder their commercialization. Herein, we propose a ternary composite ink system (graphene nanoplatelets/carbon black/PEDOT:PSS , G-C-P ink) by utilizing synergistic effect three different components. This exhibits superior rheological properties, enabling patterned sensors on textile substrates through high-resolution screen printing. The interplay materials overcomes limitations single/dual endows with ultrahigh sensitivity (gauge factor = 1628 at 155-200% strain), broad working range (0-200% robust durability (>5000 cycles). Furthermore, stretchable interconnects based silver fractal dendrites were integrated to extend sensor array. Both directly screen-printed onto textile, achieving seamless compatibility industrial manufacturing processes. Integration printed circuit boards enabled glove, demonstrating gesture recognition object-grasping recognition. work establishes scalable paradigm for high-performance provides new possibilities commercialization systems.
