Most strain sensors have tensile properties of less than 20% and have limitations regarding body motion linkage, complex sensor structure, and motion nonreliability. To address these problems, we developed a high tension and high sensitivity sensor with a gauge factor over 40 and tensile stress about 50%. Polydimethylsiloxane (PDMS) was selected as the flexible substrate to ensure tensile strength, and polyaniline (PANI) was used to measure the resistance changes in the sensor. In particular, problems regarding poor uniformity of PANI on PDMS were resolved by surface treatment of the PDMS, wherein PANI polymerization was performed sequentially after forming a self-assembled monolayer (SAM) on the PDMS substrate. O2 plasma and (3-aminopropyl)triethoxysilane were used to form the SAM. It is expected that this sensor can obtain stable characteristics even under high tensile stress through the evenly formed PANI films on the surface-treated PDMS substrate and may be used in various flexible sensor applications.<\/jats:p>","DOI":"10.3390\/s22072741","type":"journal-article","created":{"date-parts":[[2022,4,3]],"date-time":"2022-04-03T06:04:01Z","timestamp":1648965841000},"page":"2741","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Dilute Polymerization of Aniline on PDMS Substrate via Surface Modification Using (3-Aminopropyl)Triethoxysilane for Stretchable Strain Sensor"],"prefix":"10.3390","volume":"22","author":[{"given":"Chang-Joo","family":"Yim","sequence":"first","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Dongguk University-Seoul, Seoul 04620, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji-Yeon","family":"Choy","sequence":"additional","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Dongguk University-Seoul, Seoul 04620, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hae-Kyung","family":"Youi","sequence":"additional","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Dongguk University-Seoul, Seoul 04620, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2192-1410","authenticated-orcid":false,"given":"Jung-Hoon","family":"Hwang","sequence":"additional","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Dongguk University-Seoul, Seoul 04620, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eun-Bee","family":"Jo","sequence":"additional","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Dongguk University-Seoul, Seoul 04620, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun-Ho","family":"Lee","sequence":"additional","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Dongguk University-Seoul, Seoul 04620, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1127-5766","authenticated-orcid":false,"given":"Hyun-Seok","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Dongguk University-Seoul, Seoul 04620, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"815","DOI":"10.1016\/0039-9140(91)80261-W","article-title":"Review: Polyaniline a novel polymeric material","volume":"38","author":"Akheel","year":"1991","journal-title":"Talanta"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"6480","DOI":"10.1021\/la970537z","article-title":"Selective deposition of conducting polymers on hydroxyl-terminated surfaces with printed monolayers of alkylsiloxanes as templates","volume":"13","author":"Huang","year":"1997","journal-title":"Langmuir"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"608","DOI":"10.1021\/cm990537f","article-title":"Conducting polymer nanocomposites: A brief overview","volume":"12","author":"Gangopadhyay","year":"2000","journal-title":"Chem.
