Here, an electromagnetically induced transparency (EIT)-like THz metasurface integrated with a 7\u00a0\u00b5m ultra-thin microfluidic channel is engineered to enable reliable moisture quantification under variable temperature conditions. By leveraging ultra-thin analyte confinement, the electromagnetic interaction between the dielectric medium and the confined resonant field is markedly intensified, effectively mitigating bulk absorption effects and converting subtle moisture perturbations into readily resolvable non-radiative damping responses. With an injection volume of only 10\u00a0\u00b5L, the sensor exhibits a pronounced amplitude response over the 0\u2013700\u00a0ppm range, yielding an estimated limit of detection (LOD) of 48\u00a0ppm based on the system noise floor, over an experimentally evaluated non-zero concentration range of 50\u2013700\u00a0ppm (\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    =0.9976). Furthermore, temperature variation from 25\u00b0C to 80\u00b0C predominantly modulates the resonance amplitude while inducing minimal spectral displacement, thereby establishing a stable amplitude-dominant sensing regime with minimal spectral drift. To further suppress thermal interference, a second-order polynomial compensation model was developed, reducing the standard deviation of transmittance fluctuations from 1.25 to 0.08 after compensation. This work offers a promising strategy for THz sensing in lossy liquid media and provides useful insights for the future development of condition-monitoring systems for power equipment.\n                  <\/jats:p>","DOI":"10.1364\/ao.606025","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T14:09:11Z","timestamp":1788962951000},"page":"9798","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Temperature-compensated microfluidic terahertz metasurface for trace moisture quantification in insulating oil"],"prefix":"10.1364","volume":"65","author":[{"given":"Yonggang","family":"Zhang","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00q9atg80","id-type":"ROR","asserted-by":"publisher"}]},{"name":"Southeast University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Liu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00q9atg80","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lanju","family":"Liang","sequence":"additional","affiliation":[{"name":"Zaozhuang University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7481-8516","authenticated-orcid":true,"given":"Xin","family":"Yan","sequence":"additional","affiliation":[{"name":"Zaozhuang University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8985-0244","authenticated-orcid":true,"given":"Haiyun","family":"Yao","sequence":"additional","affiliation":[{"name":"Zaozhuang University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-3276-744X","authenticated-orcid":true,"given":"Zhenhua","family":"Li","sequence":"additional","affiliation":[{"name":"Zaozhuang University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziqun","family":"Wang","sequence":"additional","affiliation":[{"name":"Zaozhuang University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofei","family":"Hu","sequence":"additional","affiliation":[{"name":"Zaozhuang University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang","family":"Hu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00q9atg80","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuelong","family":"Yu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00q9atg80","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-3437-3637","authenticated-orcid":true,"given":"Suwei","family":"Zhou","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00q9atg80","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiaodi","family":"Zhen","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00q9atg80","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-0661-0269","authenticated-orcid":true,"given":"Yulin","family":"He","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/00q9atg80","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Bao","sequence":"additional","affiliation":[{"name":"Zaozhuang University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manqiu","family":"Xie","sequence":"additional","affiliation":[{"name":"Zaozhuang University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2026,9,25]]},"reference":[{"key":"ao-65-28-9798-R1","doi-asserted-by":"publisher","first-page":"133","DOI":"10.1109\/JPROC.2010.2081330","type":"journal-article","volume":"99","author":"Huang","year":"2011","journal-title":"Proc.
