具有高分辨率和高变形可靠性的柔性温度传感器是可穿戴式皮肤温度监测电子设备的主要研究热点。本研究通过在热塑性聚氨酯(TPU)纤维表面原位生长聚(3，4-乙二氧基噻吩基)(PEDOT)，制备了一种类纤维温度传感器。该温度传感器的灵敏度为0.95%中心点~(-1)，线性范围为20~40℃。最重要的是，该传感器实现了0.2？的高温度分辨率。由于其结构，温度敏感纤维很容易嵌入到纺织品中。通过将纤维缝制成S形状的普通纺织品，即使织物拉伸到140%，应变的干扰也几乎可以避免。此外，所获得的传感器可以在运动过程中监测皮肤温度，这表明该传感器在医疗保健和疾病诊断中的应用潜力。
Flexible temperature sensors with high resolution and good reliability under deformation are a major research focus for wearable electronic devices for skin temperature monitoring. In this study, a fiber-like temperature sensor is fabricated by in situ growing poly(3,4-ethylenedioxythiophene) (PEDOT) on the surface of thermoplastic polyurethane (TPU) fiber. The temperature sensor achieves a high sensitivity of 0.95%center dot ?(-1) with a high linearity between 20 and 40 ?. Most importantly, the sensor achieves a high temperature resolution of 0.2 ?. Due to its structure, the temperature-sensitive fiber is easily embedded into textiles. By sewing the fiber into normal textiles in an S-shape, the interference of strain can be nearly avoided, even when the textile is stretched to 140%. Also, the obtained sensors can monitor skin temperature during exercise, which demonstrates the potential of the sensor's application in healthcare and disease diagnosis.
