基于纳米材料的柔性应变传感器近年来发展迅速。在这里，我们提出了一种基于聚二甲基硅氧烷和碳纳米管(CNTs)和石墨烯量子点(GQD)的柔性应变传感器。采用不同重量比的碳纳米管和碳纳米管作为应变传感器的敏感单元。在分析了传感器的电流-电压曲线和应变效应后，我们得出结论：GQD的引入对提高传感器的灵敏度起到了重要作用。所制备的应变传感器的量规系数在0~841.42之间。
Nanomaterial-based flexible strain sensors have developed rapidly in recent years. Here, we propose a flexible strain sensor based on polydimethylsiloxane with carbon nanotubes (CNTs) and graphene quantum dots (GQDs). Different weight ratios of CNTs and GQDs were used as the sensitive units of the strain sensors. After analyzing the results of current–voltage curves and the strain effects of the sensors, we concluded that the introduction of GQDs played an important role in improving the sensitivity of the sensors. The gauge factor of the as-prepared strain sensors ranges from 0 to 841.42.
