In order to achieve the effective testing of CFRP materials, increasing the operating frequency or improving the coil structure is a common method used by researchers. Higher or wider operating frequencies make the design of the ADC\u2019s conditioning circuit complex and difficult to miniaturize. In this paper, an LC resonator based on inductance-to-digital converters (LDCs) is designed to easily detect the resonant frequency response to the state of the material under test. The reasonableness of the coil design is proven by simulation. The high signal-to-noise ratio (SNR) and detection sensitivity of the LC resonator are demonstrated through comparison experiments involving multiple probes. The anti-interference capability of the LC resonator in CFRP defect detection is demonstrated through various interference experiments.<\/jats:p>","DOI":"10.3390\/s24113449","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T09:33:31Z","timestamp":1716802411000},"page":"3449","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Non-Destructive Testing of Carbon Fiber-Reinforced Plastics (CFRPs) Using a Resonant Eddy Current Sensor"],"prefix":"10.3390","volume":"24","author":[{"given":"Ming","family":"Ma","sequence":"first","affiliation":[{"name":"School of Life Sciences, Tiangong University, Tianjin 300387, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiyu","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Control Science and Engineering, Tiangong University, Tianjin 300387, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5977-1713","authenticated-orcid":false,"given":"Ronghua","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Artificial Intelligence, Tiangong University, Tianjin 300387, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Control Science and Engineering, Tiangong University, Tianjin 300387, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Artificial Intelligence, Tiangong University, Tianjin 300387, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bailiang","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Artificial Intelligence, Tiangong University, Tianjin 300387, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"189","DOI":"10.1109\/JSEN.2018.2876199","article-title":"Extraction of LOI Features from Spectral Pulsed Eddy Current Signals for Evaluation of Ferromagnetic Samples","volume":"19","author":"Wen","year":"2019","journal-title":"IEEE Sens.
