The flexible strain sensors that integrate optical and electric signal are rather limited, although the flexible sensor community has witnessed increased progresses. Herein, we have fabricated stretchable polymer composites showing both mechanically modulated fluorescence and electric resistance by using polyester elastomer, zinc phthalocyanine (ZnPc) and silver nanowires (Ag NW) as basic components. Specifically, the strain variation in the range of 0∼30% and 50%∼400% can be well correlated with the alternation of electric resistance and red fluorescence of flexible composites, respectively. The present work will open the way for the large-scale fabrication of multi-functional flexible strain sensors.

集成了光信号和电信号的柔性应变传感器相当有限，尽管柔性传感器领域已经取得了进步。在这里，我们通过使用聚酯弹性体，锌酞菁（ZnPc）和银纳米线（Ag NW）作为基本成分，制造了显示出机械调制的荧光和电阻的可拉伸聚合物复合材料。具体地，应变变化在0〜30％和50％〜400％的范围内可以分别与挠性复合材料的电阻和红色荧光的交替很好地相关。当前的工作将为大规模制造多功能柔性应变传感器开辟道路。
