摘要
柔性可穿戴电子器件因其在人体运动检测、健康监测、人工智能和人机交互等领域的广泛应用备受关注.柔性传感器作为人体和环境交互的重要组成部分,具有良好的柔韧性和感知外部刺激的能力.外界施加的压力刺激以及人体自身或者环境温度的变化都会对个人生活产生影响.因此,目前的研究重点在于开发具有压力-温度双功能传感性能的柔性传感器.本文综述了压力-温度双功能柔性传感器最近的研究进展,包括传感机制、双功能传感器的设计和其在生物医学方面的应用.通过集成不同类型的传感器以及设计由多功能材料和微结构构成的单个双功能传感器,可实现对压力和温度的同时检测.文章最后总结了柔性压力-温度双功能传感器面临的挑战和问题,并对其未来发展进一步展望.
Abstract
The review summarizes the recent research progress of pressure-temperature dual-functional flexible sen-sors,including the sensing mechanisms,the design of dual-functional sensors,and their applications in biomedi-cine.The sensing mechanisms of the sensors include electrical signal mechanisms(resistance,voltage,and capaci-tance mechanisms)and non-electrical signal mechanisms(optical and magnetic mechanisms).Then,the design strat-egies of pressure-temperature dual-functional flexible sensors are discussed,including the integration of different types of sensors and the design of single dual-functional sensors composed of multifunctional materials and micro-structures.Finally,the applications of pressure-temperature dual-functional flexible sensors in human motion detec-tion,health monitoring,artificial intelligence,and human-machine interaction are introduced.Based on this,the problems of dual-functional flexible sensors are summarized,and the future development prospects are discussed.
