摘要
在现代科技飞速发展的背景下,可穿戴电子设备以其轻便、柔软、易于携带的特性,在医疗监测、康复治疗以及环境监控等多个领域展现出了巨大的应用潜力.这一趋势不仅促进了相关技术的进步,还对柔性储能材料与传感技术提出了更高的要求.因此,探索与开发成本低廉、性能卓越且易于集成的柔性充电电池和应变传感器成为研究的重点,这对推动可穿戴电子技术的发展具有深远的理论与实践意义.针对柔性摩擦电传感器在生产过程中存在的成本高、工艺复杂、环保性不佳等问题,提出了一种采用纸基导电银浆的柔性摩擦电传感器新方案.该传感器在监测人体运动状态方面表现出了优异的性能,能准确识别肘部和腕部的弯曲角度,区分不同的运动类型(如行走、快走、跑步)及健身动作(如踮脚、深蹲、抱腹跳),并能有效计算行走频率及健身次数.这些特性使其在人体运动监测领域展现出广阔的应用前景.
Abstract
In the context of the rapid development of modern science and technology,wearable electronic devices,with their lightweight,soft and easy to carry characteristics,have shown great application potential in many fields such as medical monitoring,rehabilitation treatment and environmental monitoring.This trend not only promotes the progress of related technologies,but also poses a higher challenge to flexible energy storage materials and sensing technologies.Therefore,the exploration and development of flexible rechargeable batteries and strain sensors with low cost,excellent performance and easy integration has become the focus of research,which has far-reaching theoretical and practical significance for promoting the development of wearable electronic technology.Aiming at the problems of high cost,complicated process and poor environmental protection in the production process of flexible triboelectric sensor,a new scheme of flexible triboelectric sensor using paper-based conductive silver paste was proposed.The sensor has shown excellent performance in monitoring the state of human movement,can accurately identify the bending angle of the elbow and wrist,distinguish different types of exercise(such as walking,fast walking,running)and fitness actions(such as tiptoe,squat,belly jump),and can effectively calculate the walking frequency and fitness times.These characteristics make it show a broad application prospect in the field of human motion monitoring.
