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.
近年来，灵活便携电子产品蓬勃发展，人们对成本效益高且定制化的多功能设备的需求非常高。在这里，我们报告了一种使用导电油墨书写的巧妙折纸分层传感器阵列（OHSA）。得益于折纸作为一种可控的分层框架来加载油墨材料，我们已经证明 OHSA 具有独特的时间-空间分辨、高区分模式识别（TSR-HDPR）特性，使其成为一种智能传感设备，可同时感测和区分复杂的物理和化学刺激物，包括温度、相对湿度、光和挥发性有机化合物（VOCs）。特别重要的是，OSHA 在区分 VOCs 的结构异构体和手性对映异构体方面表现出非常高的灵敏度——为多个尺度的各种独特机会开辟了大门。
