近年来，柔性和便携式电子产品蓬勃发展，对高性价比和量身定做的多功能设备的需求非常高。在这里，我们报告了一种巧妙的折纸分层传感器阵列(OHSA)，它是用导电墨水写成的。由于折纸作为加载墨水材料的可控分层框架，我们已经证明OHSA具有独特的时空分辨率、高分辨率模式识别(TSR-HDPR)功能，使其成为一种同时检测和区分复杂物理和化学刺激的智能传感设备，包括温度、相对湿度、光和挥发性有机化合物(VOC)。特别重要的是，OSHA在区分VOCs的结构异构体和手性对映体方面表现出非常高的敏感性-打开了在几个长度尺度上各种独特机会的大门。
Recent years have witnessed thriving progress of flexible and portable electronics, with very high demand for cost-effective and tailor-made multifunctional devices. Here, we report on an ingenious origami hierarchical sensor array (OHSA) written with a conductive ink. Thanks to origami as a controllable hierarchical framework for loading ink material, we have demonstrated that OHSA possesses unique time-space-resolved, high-discriminative pattern recognition (TSR-HDPR) features, qualifying it as a smart sensing device for simultaneous sensing and distinguishing of complex physical and chemical stimuli, including temperature, relative humidity, light and volatile organic compounds (VOCs). Of special importance, OSHA has shown very high sensitivity in differentiating between structural isomers and chiral enantiomers of VOCs – opening a door for wide variety of unique opportunities in several length scales.
