复合纸基柔性传感器力学性能与人体运动关系研究

Study on the Relationship Between Mechanical Properties and Human Motion of Composite Paper Based Flexible Sensor

柔性可穿戴传感器可适应人体皮肤的形变,有着良好的环境匹配性,在人体健康与运动监测等相关领域有着不小的市场需求。近年来,纸张材料以其柔性、绿色环保、低成本等优势,在柔性传感器领域展现出较大的应用潜力。基于此,简述了纸基柔性传感器的分类与工作机理,以动态聚合物与MXene纸基传感材料相结合,制备复合纸基柔性传感器,并对复合纸基柔性传感器的力学性能进行测试与分析。结果表明,该传感器的拉伸强度和抗弯曲能力较好,力学性能得到显著增强。该传感器可应用到人体手指关节、颈椎等部位的运动监测,也可用于运动状态下人体心电信号的监测。今后纸基柔性传感器的功能性会更加完善,满足更多应用场景需求。

Flexible wearable sensors can adapt to the deformation of human skin,has good environmental matching,and has a large market demand in human health and motion monitoring and other related fields.In recent years,paper materials have shown strong application potential in the field of flexible sensors with their advantages of flexibility,green environmental protection and low cost.Based on this,the classification and working mechanism of paper-based flexible sensors are briefly described.A composite paperbased flexible sensor is prepared by combining dynamic polymer with MXene paper-based sensing material.The mechanical properties of the composite paper-based flexible sensor are tested and analyzed.The sensor can be applied to the motion monitoring of finger joints,cervical vertebrae and other parts of the human body,and can also be used to monitor the ECG signal of the human body in the state of motion.In the future,the functionality of paper-based flexible sensors will be more perfect to meet the needs of more application scenarios.
