Abstract

In order to further improve the detection performance of the wearable heart rate sensor for human physiological and biochemical signals and body kinematics performance, the wearable heart rate sensor module was optimized by using nanofibers. Nanoparticle-doped graphene films were prepared by adding nanoparticles to a graphene oxide solution. The prepared film was placed in toluene, and the nanoparticles were removed to complete the preparation of a graphene film with a porous microstructure. The graphene film and the conductive film together formed a wearable heart rate sensor module. The strain response test of the porous graphene film wearable heart rate sensor module verifies the validity of the research in this paper. The resistance change of the wearable heart rate sensor module based on the PGF-2 film is 8 to 16 times higher than that of the RGO film, and the sensitivity is better, proving that the sensor module designed by this method shows significant application potential in human motion detection.

摘要

为了进一步提高人体生理生化信号和运动学性能的可穿戴心率传感器的检测性能，通过使用纳米纤维对可穿戴心率传感器模块进行了优化。通过向氧化石墨烯溶液中添加纳米粒子来制备掺杂纳米颗粒的石墨烯薄膜。将制备好的薄膜放置在甲苯中，去除纳米颗粒，完成具有多孔微观结构的石墨烯薄膜的制备。石墨烯薄膜和导电薄膜共同构成了可穿戴心率传感器模块。多孔石墨烯薄膜可穿戴心率传感器模块的应变响应测试验证了本文研究的有效性。基于 PGF-2 薄膜的可穿戴心率传感器模块的电阻变化比 RGO 薄膜高 8 到 16 倍，灵敏度更好，证明了这种方法设计的传感器模块在人体运动检测中具有显著的应用潜力。
