柔性温度传感器能够检测和传输来自人体、环境和电子设备的温度数据，在电子皮肤、人机交互和灾害预防系统中具有巨大的应用潜力。尽管如此，制造具有卓越传感性能的柔性温度传感器仍然是一项艰巨的任务，这主要是由于构建具有高灵敏度的本质柔性传感元件的复杂过程。在这项研究中，介绍了一种简便的原位两步合成方法来制造柔性纤维状NiO/碳纳米管纤维（CNTF）复合材料。由此产生的 NiO/CNTF 柔性温度传感器表现出出色的变形能力和温度传感特性，涵盖广泛的工作范围（−15 至 60 °C）和高灵敏度（最大 TCR 为 -20.2% °C ^-1和 B 值为 3332 K）。重要的是，使用有限元分析模拟彻底检查了传感器在各种应用条件下的机械和热行为。此外，温度传感器可以有效捕获可穿戴应用中的各种热信号。值得注意的是，开发了温度监测和预警系统，以防止电子设备异常热失控引起的火灾事故。

Robust Fiber-Shaped Flexible Temperature Sensors for Safety Monitoring with Ultrahigh Sensitivity

Flexible temperature sensors capable of detecting and transmitting temperature data from the human body, environment, and electronic devices hold significant potential for applications in electronic skins, human–machine interactions, and disaster prevention systems. Nonetheless, fabricating flexible temperature sensors with exceptional sensing performance remains a formidable task, primarily due to the intricate process of constructing an intrinsically flexible sensing element with high sensitivity. In this study, a facile in situ two-step synthetic method is introduced for fabricating flexible fiber-shaped NiO/carbon nanotube fiber (CNTF) composites. The resulting NiO/CNTF flexible temperature sensors demonstrate outstanding deformability and temperature sensing characteristics, encompassing a broad working range (−15 to 60 °C) and high sensitivity (maximum TCR of −20.2% °C⁻¹ and B value of 3332 K). Importantly, the mechanical and thermal behaviors of the sensor in various application conditions are thoroughly examined using finite element analysis simulations. Moreover, the temperature sensors can effectively capture diverse thermal signals in wearable applications. Notably, a temperature monitoring and warning system is developed to prevent fire accidents resulting from abnormal thermal runaway in electronic devices.
