生物力学与生物分子作为反映人体生理状态的重要生理参数,在传感检测过程中往往依赖于不同的传感机理,传统单一功能的传感器难以实现二者的高效同步监测。开发能够融合多种传感机理的多功能传感器,是实现人体生理信息全方位监测及精准健康管理的关键。在粘胶织物(VCFs)表面构筑均匀分布的银纳米颗粒(AgNPs),通过整合AgNPs的局域表面等离子体共振效应和优异的电学性质以及VCFs的柔韧性和优异的吸湿性,有效融合压阻/光学传感机理,制备了柔性VCFs@Ag压阻/光学传感器并研究了其性能。结果表明压阻传感器的灵敏度为49.69kPa^-1、线性度R²=0.94;光学传感器的检测限为10nmol/L,可用于人体生物力学与生物分子信息的协同感知。

Biomechanics and biomolecules,as two types of important physiological parameters reflecting the physiological state of the human body,often rely on different sensing mechanisms in the sensing and detection process,and it is difficult for traditional single-function sensors to realize efficient and simultaneous monitoring of both.The development of multifunctional sensors capable of integrating multiple sensing mechanisms is the key to achieving comprehensive monitoring of human physiological information and accurate health management.Uniformly distributed silver nanoparticles (AgNPs) were constructed on the surface of viscose fabrics (VCFs),and combining the local surface plasmon resonance effect and excellent electrical properties of silver nanoparticles,as well as the flexibility and excellent hygroscopicity of VCFs,the piezoresistive/optical sensing mechanism was effectively integrated to prepare a flexible VCFs@Ag piezoresistive/optical sensor,and its performance was studied.Results indicated that the sensitivity of the piezoresistive sensor was 49.69kPa^-1 with high linearity (R²=0.94).The detection limit of the optical sensor was 10nmol/L,which could be applied in the synergistic sensing of human biomechanics and biomolecular information.
