Abstract

Purpose Passive chipless RFID (radio frequency identification) sensors, devoid of batteries or wires for data transmission to a signal reader, demonstrate stability in severe conditions. Consequently, employing these sensors for metal crack detection ensures ease of deployment, longevity and reusability. This study aims to introduce a chipless RFID sensor design tailored for detecting metal cracks, emphasizing tag reusability and prolonged service life. Design/methodology/approach The passive RFID sensor is affixed to the surface of the aluminum plate under examination, positioned over the metal cracks. These cracks alter the electrical length of the sensor, thereby influencing its amplitude-frequency characteristics. Hence, the amplitude-frequency profile generated by various metal cracks can effectively ascertain the occurrence and orientation of the cracks. Findings Simulation and experimental results show that the proposed crack sensing tag produces different frequency amplitude changes for four directions of cracks and can recognize the crack direction. The sensor has a small size and simple structure, which makes it easy to deploy. Originality/value This research aims to deploy crack detection on metallic surfaces using passive chipless RFID sensors, analyze the amplitude-frequency characteristics of crack formation and distinguish cracks of varying widths and orientations. The designed sensor boasts a straightforward structural design, facilitating ease of deployment, and offers a degree of reusability.

开发用于金属表面裂缝检测的无芯片 RFID 传感器

目的无源无芯片 RFID（射频识别）传感器没有电池或用于向信号读取器传输数据的电线，在恶劣条件下也能保持稳定。因此，使用这些传感器进行金属裂纹检测，可确保其易于部署、使用寿命长且可重复使用。本研究旨在介绍一种专为检测金属裂缝而设计的无芯片 RFID 传感器，强调标签的可重复使用性和延长使用寿命。这些裂缝会改变传感器的电气长度，从而影响其振幅-频率特性。模拟和实验结果表明，所提出的裂纹传感标签能对四个方向的裂纹产生不同的频率振幅变化，并能识别裂纹方向。本研究旨在利用无源无芯片 RFID 传感器对金属表面进行裂纹检测，分析裂纹形成的幅频特性，并区分不同宽度和方向的裂纹。所设计的传感器结构设计简单明了，便于部署，并具有一定的重复使用性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
