摘要

Flexible sensors, due to their unique advantages, are anticipated to find applications in electronic skin, human monitoring, human–computer interaction, and other fields. Among these, flexible strain sensors have garnered significant attention owing to their broad detection range, high sensitivity, and robust anti-interference capability. This paper presents a method for constructing a uniform conductive network within a thermoplastic polyurethane (TPU) matrix by incorporating ionic liquids (ILs) and carbon black nanoparticles (CB). The resulting flexible strain sensor exhibits sensitivities of 1.16 and 2.15 at 0–60% and 60–200% strain levels, respectively. This sensor can accurately monitor various tensile signals and demonstrates response recovery times of 130 ms and 98 ms in tensile mode, and 191 ms and 195 ms in bending mode. Its output signal remains stable after over 200 cycles of 50% strain, indicating excellent durability and stability. Finally, by encapsulating and sewing it onto clothing, it can generate SOS distress signals in two ways, making it a potential tool for emergency calls. This flexible strain sensor showcases superior performance and immense potential in the realm of wearable electronics.
