摘要
柔性传感器可将外界的机械信号转化为电信号输出,以记录变形、运动时的相关数据变化。相较于传统的刚性传感器,如金属传感器和半导体传感器,柔性传感器有着易于拉伸、易于多维度变形和高回复等优异性能,可被应用到人体肢体运动检测、蒸汽检测及机器人运行控制等,逐渐成为智能穿戴领域研究的热点。柔性传感器可通过聚合物与导电填料共混或进行表面涂覆整理制备,从而具有柔性、可拉伸性、可回复性以及优异的导电性能,使其能够根据外界刺激作出相应电信号响应。对近些年柔性传感器研究中涉及的聚合物基体及导电填料进行简介,对基于苯乙烯-丁二烯-苯乙烯嵌段共聚物(poly (styrene-butadiene-styrene),SBS)的柔性传感器的制备方法和性能等方面进行详细综述,最后对SBS柔性传感器面临的问题作出简单讨论。
Flexible sensors can convert external mechanical behaviors into electrical signals output to record relevant data changes during deformation and movement. Comparing with the traditional metal and semiconductor sensors, flexible sensors have excellent performances such as high stretchability, ability of multi-scale deformation, high recoverability, and so on, which can be applied to human body movement detection, steam detection, and robot operation control, etc., becoming the hot spot of the study of smart wearables. Flexible sensors are generally prepared by blending polymers and conductive fillers or surface finishing to make them flexible, stretchable, recoverable and conductive, so as to respond to external stimuli. This article gives a brief introduction to the polymer matrix and conductive fillers studied in recent years, a detailed overview of the preparation methods and performance of poly(styrene-butadiene-styrene)(SBS) based flexible sensors, and finally the problems on SBS flexible sensor development are discussed briefly.
