【摘要】 近几年,可穿戴电子设备的需求量日益上升,可穿戴技术越来越受到国内外研究者的青睐。作为可穿戴电子设备的核心部件之一的柔性传感器通过可以感受外界不同的刺激来做出相应的响应,这在医疗健康检测与人机交互领域应用广泛。然而传统的传感器因为体积大、柔性差使得制成的可穿戴电子设备佩戴不舒适并且成本高昂。最近发展迅速的纳米技术为柔性传感器的制作提供了新的方向,纳米技术在提升穿戴舒适度与提高传感器性能上具有重要的研究意义。本研究针对医疗健康监测领域和人机交互领域的巨大需求,以柔性压阻传感器为核心,以实现宽应变、快响应、低限检测为目的,开展了基于纳米技术的柔性压阻传感器的制备与研究,研究内容如下:1.设计并制作了黑磷-金柔性压阻传感器。该传感器通过使用黑磷-金纳米复合材料对海绵骨架修饰而制成,得益于密胺绵优异的机械性能和黑磷-金纳米复合材料的导电性,所制成的柔性压阻传感器具有优异的性能参数,比如:较宽的应变范围（0～90%）,合理的规范因子GF（0.838/1.50）,快速响应时间（10 ms）,以及良好的重复性与线性度。2.设计并制作了碳化钛-金柔性压阻传感器,该传感器由使用碳化钛-金纳米复合材料修饰后的密胺绵与纸基碳浆叉指电极相贴合而制成。该传感器通过海绵与碳浆电极的接触效应使得自身保持着出色的性能,如:高灵敏度(32.34 KPa^-1)、快速响应时间（32 ms）与回复时间（24 ms）,同时具有较低的检测限与良好的重复性。3.完成了柔性压阻传感器的相关应用研究。利用本研究制作出的两种柔性压阻传感器,进行了健康监测和人机交互的应用。例如,监测人体的运动（如:手指、手腕、膝盖弯曲）及更加微小的人体生命活动（如:心跳、脉搏）。此外,利用黑磷-金柔性压阻传感器制作出了可穿戴式的智能手套,完成了相关结构设计、硬件设计以及软件的设计,实现了对机械手的精确控制。更多还原

【Abstract】 Wearable electronic gadget demand has recently surged,and both domestic and international scholars are growing increasingly interested in wearable technology.Because they can perceive a wide range of external inputs,flexible sensors,which are important to wearable electronics,have a wide range of applications in the domains of human-computer interaction and medical health assessment.Unfortunately,traditional sensors are expensive and unpleasant to wear due to their bulk and lack of flexibility.Nanotechnology has important research implications for improving sensor performance and wearability,and recent breakthroughs have shifted the manufacture of flexible sensors in a new direction.Flexible piezoresistive sensors based on nanotechnology are developed and researched in this thesis to address the enormous demand in the fields of medical health monitoring and human-computer interaction,with the goal of resolving the issue of sensor wide strain,quick response,and low limit detection:1.A flexible piezoresistive sensors was produced by incorporating black phosphorus-gold nanocomposites into the sponge skeleton.Thanks to the excellent elasticity and mechanical characteristics of the melamine and the electrical conductivity of the black phosphorus-gold nanocomposites,the flexible piezoresistive sensors have excellent performance parameters,including a wide strain range（0-90%）,a reasonable gauge factor GF（0.838/1.50）,fast response times（10 ms）and recover times（20 ms）,and good repeatability and linearity.2.A flexible piezoresistive sensor was designed and built using a titanium carbide-gold nanocomposite modified melamine sponge bonded to a paper-based carbon pulp forked finger electrode.The contact effect between the sponge and the carbon paste electrode allows the sensor to maintain exceptional performance,including high sensitivity(32.34 KPa^-1),quick response times（32 ms）and recover times（24 ms）,as well as low detection and good repeatability.3.Research on applications by using the prepared flexible piezoresistive sensors.The two flexible piezoresistive sensors developed in this thesis were used for health monitoring and human-computer interface applications.They can be used to track human movement（for example:finger,wrist,and knee flexion）as well as other minute human life activities（e.g.heartbeat,pulse）.The black phosphorus-gold flexible piezoresistive sensor was used to produce a wearable smart glove,including completing the structural design,hardware design and software design,and finally the successful and precise control of the manipulator.更多还原
