In this research, we developed a wearable temperature-sensing element by dip dyeing threads in poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) (p-type conducting polymer) solution. The PEDOT:PSS was used to dye the textile and it exhibited negative temperature coefficient characteristics in which the resistance decreases as the temperature increases. The fabricated temperature-detection thread achieved a sensitivity of 167.1 Ω/°C with 99.8% linearity in the temperature range of -50 °C to 80 °C. We anticipate that temperature sensors that apply our technology will be made as stitch- or textile-type for wearable devices, and they will be widely adopted for different applications such as in fitness, leisure, healthcare, medical treatment, infotainment, industry, and military applications, among others.
在这项研究中，我们通过将聚（3,4-亚乙基二氧噻吩）聚苯乙烯磺酸盐（PEDOT:PSS）（p 型导电聚合物）溶液浸染在纤维上来开发可穿戴温度感应元件。PEDOT:PSS 用于对纺织品进行染色，其表现出负温度系数特性，即随着温度的升高电阻减小。所制造的温度检测线在-50°C 至 80°C 的温度范围内实现了 167.1 Ω/°C 的灵敏度和 99.8%的线性度。我们预计，应用我们技术的温度传感器将被制成用于可穿戴设备的缝合或纺织类型，它们将被广泛应用于各种应用，如健身、休闲、医疗保健、医疗、信息娱乐、工业和军事应用等。
