摘要：

本文采用简单的纺丝（干喷湿纺）方法将石墨烯和炭黑混合纤维素纺成温度响应纤维，提出了一种使用石墨烯和炭黑纤维制造可穿戴式温度传感器新方法。这种传感器具有高抗拉强度、较短的响应时间（6.5 s）和良好的温度恢复时间（25.5 s）。在多次施加机械形变后，其响应保持稳定。通过简单的工艺将其集成在织物中，可由人穿着监控皮肤温度，且具有较强的抗干扰性。上述结果表明：基于导电纳米改性纺织纤维材料的可穿戴温度传感器具有巨大的应用潜力。

Abstract:

This study employs a simple spinning（dry-jet wet spinning） method to spin graphene and carbon black mixed with cellulose into temperature-responsive fibers， proposing a novel approach for fabricating wearable temperature sensors using graphene and carbon black fibers. The characteristics of this sensor include high tensile strength， short response time（6.5 s）， and good temperature recovery time（25.5 s）. After multiple mechanical deformations of the sensor， its performance remains stable. The wearable temperature sensor is mixed into fabrics through textile technology and can be worn by people to monitor skin temperature and has strong anti-interference properties. This research indicates that wearable temperature sensor based on conductive nano-modified textile fiber materials has great value and future in application.

Key words: wearable temperature sensor, fiber-based electronic device, graphene-enhanced, fast response
