摘要
柔性温度传感器由于其灵活、薄、轻等优点而引起了人们越来越多的兴趣,是柔性电子发展的必然趋势。以纳米多孔碳(NP-C)为温敏材料,采用滴涂法将温敏浆料涂覆在电极上制备出柔性电阻型温度传感器,该传感器的温敏单元大小仅0.1 cm^(2)。通过扫描电子显微镜(SEM)、X射线衍射(XRD)、拉曼光谱和X射线光电子能谱分析对NP-C的形貌、结构和组成进行了表征,并搭建平台对传感器进行温敏性能测试。结果表明:该传感器的测温范围宽达-50~100℃,呈负温度系数,在20~80℃内,传感器的线性度超过0.9907,灵敏度高达0.6112%/℃;80℃时,该传感器的响应/恢复时间仅需10.1 s/16.4 s,且迟滞性小,稳定性良好。该成果在可穿戴电子产品、机器人技术等领域具有较大的应用潜力。
The flexible temperature sensors have gained a growing interest due to their advantage of flexibility,thinness and lightness,which makes an inevitable trend in the development of flexible electronics.A flexible resistive temperature sensor is fabricated using nanoporous carbon(NP-C)as temperature sensitive material,flexible resistive type temperature sensor is prepared by coating temperature sensitive slurry on electrode via drop-coating method.And the size of the temperature-sensitive unit of the sensor is only 0.1 cm^(2).Through scanning electron microscopy(SEM),X-ray diffraction(XRD),Raman spectroscopy and X-ray photoelectron spectroscopy,characterizations of morphology,structure and composition of the NP-C are conducted and a platform is built to test the thermosensitive performance of sensor.The results indicate that the temperature measurement range of the sensor is-50~100℃,exhibiting a negative temperature coefficient.Within the range of 20~80℃,the linearity of the sensor exceeds 0.9907 and the sensitivity is 0.6112%/℃.At 80℃,the sensor response/recovery time is only 10.1 s and 16.4 s,while the sensor has little hysteresis and good stability.This achievement has great application potential in wearable electronic products,robotics,and other fields.
