摘要：

为实现对人体运动及生理信息的监测,利用静电纺丝法制备轻薄型取向碳纳米纤维膜(CNFM),并以此开发柔性应变传感器。重点分析了碳纳米纤维膜的结构及性能,讨论了CNFM的厚度、宽度及碳纳米纤维(CNF)的取向对传感性能的影响。结果表明:聚丙烯腈/石墨烯复合纳米纤维的取向度及CNFM的透光率可分别达到61.3%和48%;当牵伸方向平行于CNF的取向时,传感器的应变范围随CNF取向度的增加先减小后增大,随CNFM厚度及宽度的增加逐渐增加;当牵伸方向垂直于CNF的取向方向时,传感器的应变范围显著提高,但其敏感系数降低。该超薄透明型柔性应变传感器可贴附于皮肤表面,检测人体关节及心率、声带振动等运动与生理信息,也可应用于智能服装及微小形变监测等领域。

Abstract:

Aiming for the monitoring of human body movement and physiological information, a thin and aligned carbon nanofiber membrane (CNFM) was prepared by using the electrospinning method, and a flexible strain sensor was developed. The structures and performances of nanofiber membranes were analyzed, and the influence of thickness and width of CNFM and the alignment of carbon nanofiber (CNF) on sensing performance was discussed. The results exhibit that the aligned degree of polyacrylonitrile/graphene composite nanofibers and the transmittance of CNFM could reach 61.3% and 48%, respectively. When the stretching direction was parallel to the aligned direction of CNF, the strain range of the sensor firstly decreases and then increases with the increase of the alignment of CNF, and gradually increases with the increase of the thickness and width of CNFM. When the stretching direction was perpendicular to the CNF orientation direction, the strain range of the sensor is significantly increased, but sensitivity is decreased. The ultra-thin transparent flexible strain sensor can be attached to the skin surface to detect the motion information caused by human joint movement, and physiological information such as pulse and vocal-cord vibration. It can also be applied in the fields of smart clothing and subtle deformation monitoring.

Key words: electrospinning, carbon nanofiber membrane, flexible strain sensor, sensing performance, smart wearable device
