In this study, an Ag-based flexible resistance temperature detector (RTD) was fabricated by electrohydrodynamic (EHD) inkjet printing for the rollable solar panel of the 3U CubeSat INHA RoSAT. The sensor was formed on a polyimide (PI) substrate and protected with a PI coating. Fourier transform infrared spectroscopy and thermogravimetric analysis were used to assess the imidization, residual solvent removal, and thermal stability of the coating. The sensor was then evaluated through an eight-cycle thermal cycling test from \u221225 to 125 \u00b0C, tailored with reference to MIL-STD-1540. The coating, heat-treated up to 250 \u00b0C, showed clear imide formation and no notable mass loss below 500 \u00b0C. During thermal cycling, the sensor exhibited stable resistance behavior with a drift rate of 0.032%\/h. The derived calibration equation yielded a mean absolute error of 1.44 \u00b0C, while the temperature coefficient of resistance and hysteresis were 0.269%\/\u00b0C and 1.2% of full-scale output (FSO), respectively. These results support the feasibility of the sensor for integration with rollable solar panels and future on-orbit temperature estimation.<\/jats:p>","DOI":"10.3390\/s26196263","type":"journal-article","created":{"date-parts":[[2026,10,2]],"date-time":"2026-10-02T11:21:49Z","timestamp":1790940109000},"page":"6263","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Resistance Temperature Detector for INHA RoSAT Rollable Solar Panel Using Electrohydrodynamic Inkjet Printing"],"prefix":"10.3390","volume":"26","author":[{"given":"Jin-Young","family":"Rim","sequence":"first","affiliation":[{"name":"Department of Aerospace Engineering and the Program in Aerospace Systems Convergence, Inha University, Incheon 21999, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-4630-8553","authenticated-orcid":false,"given":"Eo-Jin","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of Aerospace Engineering and the Program in Aerospace Systems Convergence, Inha University, Incheon 21999, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]},{"given":"Chang-Yull","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Aerospace Engineering and the Program in Aerospace Systems Convergence, Inha University, Incheon 21999, Republic of Korea"},{"name":"Aerospace Systems Research Institute, Inha University, Incheon 21999, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"supervision","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bhattarai, S., Go, J.-S., Kim, H., and Oh, H.-U.
