Organic field-effect transistor (OFET)-based gas sensors have attracted attention due to their promising performance and potential for integration into flexible and wearable devices. This review examines the operating mechanisms of OFET-based gas sensors and explores methods for improving sensitivity, with a focus on porous structures. Researchers have achieved significant enhancements in sensor performance by controlling the thickness and free volume of the organic semiconductor layer. Additionally, innovative fabrication techniques like self-assembly and etching have been used to create porous structures, facilitating the diffusion of target gas molecules, and improving sensor response and recovery. These advancements in porous structure fabrication suggest a promising future for OFET-based gas sensors, offering increased sensitivity and selectivity across various applications.<\/jats:p>","DOI":"10.3390\/s24092862","type":"journal-article","created":{"date-parts":[[2024,4,30]],"date-time":"2024-04-30T08:14:31Z","timestamp":1714464871000},"page":"2862","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Enhancing Sensitivity in Gas Detection: Porous Structures in Organic Field-Effect Transistor-Based Sensors"],"prefix":"10.3390","volume":"24","author":[{"given":"Soohwan","family":"Lim","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, School of Chemical Engineering, Konkuk University, Seoul 05029, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1571-2417","authenticated-orcid":false,"given":"Ky Van","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, School of Chemical Engineering, Konkuk University, Seoul 05029, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2380-4517","authenticated-orcid":false,"given":"Wi Hyoung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, School of Chemical Engineering, Konkuk University, Seoul 05029, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4445","DOI":"10.1002\/adma.201201689","article-title":"Stable Solution-Processed Molecular n-Channel Organic Field-Effect Transistors","volume":"24","author":"Hwang","year":"2012","journal-title":"Adv.
