Nondestructive testing (NDT) is crucial technology for authenticity identification of paper‐based artworks. Emerging optical spectroscopy is an important technique of NDT at present, by which high‐bightness light, electron beams, and rays could cause permanent damage to different types of paper‐based artworks. Here, using only NDT technology, triboelectric closed‐loop sensing system (TE‐CLSS) is developed by contact electrification effect. It is composed of a stethoscope‐like triboelectric nanogenerator (SL‐TENG) and matched closed‐loop feedback circuit (CLFC), that is capable of active sensing in a similar way to a stethoscope when it makes slight contact with the surface of object. The results report that the ΔV accuracy of TE‐CLSS could achieve 0.01 V, with relative error of measurement within 3%, and average response time of 0.205 s. Furthermore, it could sense the area change of the test material layers that accurately reach millimeter level, by which different grayscale values, colored inks, and oil paintings are successfully identified. This work gives a new insight into the future NDT technologies suitable for the identification of cultural relics.

摩擦电闭环传感系统，用于纸质艺术品的真伪识别

无损检测（NDT）是纸质艺术品真伪识别的关键技术。新兴的光谱学是目前无损检测的一项重要技术，高强度的光，电子束和射线可能会对不同类型的纸质艺术品造成永久性损害。在这里，仅使用无损检测技术，就通过接触带电效应开发了摩擦电闭环传感系统（TE-CLSS）。它由类似听诊器的摩擦电纳米发生器（SL-TENG）和匹配的闭环反馈电路（CLFC）组成，当其与物体表面轻微接触时，能够以类似于听诊器的方式进行主动感应。结果报告ΔVTE‐CLSS的精度可以达到0.01 V，相对测量误差在3％以内，平均响应时间为0.205 s。此外，它可以感应到精确达到毫米级的测试材料层的面积变化，从而成功地识别出不同的灰度值，彩色墨水和油画。这项工作为未来适用于文物鉴定的无损检测技术提供了新的见识。
