In this study, a dispensing-printed SnO2-based MEMS gas sensor was developed using a sol\u2013gel-derived SnO2 precursor ink deposited directly onto a Pt-interdigitated micro-hotplate. The precursor ink was optimized for dispensing printing and subsequently annealed at 450 \u00b0C to produce a crystalline SnO2 sensing layer. XRD and FTIR analyses confirmed the formation of crystalline tetragonal rutile SnO2 and characteristic Sn\u2013O bonding, while FE-SEM revealed an interconnected particulate sensing morphology with well-distributed Sn and O. XPS further confirmed the predominant Sn4+ chemical state and the presence of lattice and surface-related oxygen species, which are beneficial for gas adsorption and surface reactions. The fabricated sensor demonstrated effective H2S sensing performance at a relatively low operating temperature of 90 \u00b0C. The response increased systematically with the H2S concentration from 10 to 100 ppb, reaching a maximum response of 3.8897 at 100 ppb. A sensitivity of 0.0282 response units per ppb was obtained from the calibration curve, demonstrating a strong concentration-dependent response in the investigated range. Additionally, the power consumption of the sensor was low (~32 mW); the sensor also exhibited a response time of approximately 153 s, although recovery was comparatively slower at approximately 277 s at 30 ppb. Furthermore, the sensor showed a substantially higher response to H2S than the investigated interfering gases, including H2, NH3, NO2, and CO. These results demonstrate that the integration of dispensing-printed SnO2 with a MEMS micro-hotplate provides a promising route toward low-temperature, miniaturized, and highly sensitive trace-level H2S sensing.<\/jats:p>","DOI":"10.3390\/s26196031","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T14:03:26Z","timestamp":1790172206000},"page":"6031","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["High-Performance SnO2 Ink for Detecting Low-Temperature H2S Gas with Advanced Dispensing Printing Technology"],"prefix":"10.3390","volume":"26","author":[{"given":"Sufaid","family":"Shah","sequence":"first","affiliation":[{"name":"College of Electronics and Information Engineering, Shenzhen University, Shenzhen 518060, China"},{"name":"National Key Laboratory of RF Heterogeneous Integration, Shenzhen University, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"conceptualization","vocabulary":"credit"}]},{"given":"Jesse Nii Okai","family":"Amu-Darko","sequence":"additional","affiliation":[{"name":"College of Physics and Optoelectronics Engineering, Shenzhen University, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"software","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-7158-682X","authenticated-orcid":false,"given":"Xingzuo","family":"Song","sequence":"additional","affiliation":[{"name":"College of Electronics and Information Engineering, Shenzhen University, Shenzhen 518060, China"},{"name":"National Key Laboratory of RF Heterogeneous Integration, Shenzhen University, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"software","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9965-3516","authenticated-orcid":false,"given":"Xiaojin","family":"Zhao","sequence":"additional","affiliation":[{"name":"National Key Laboratory of RF Heterogeneous Integration, Shenzhen University, Shenzhen 518060, China"},{"name":"College of Integrated Circuits, Shenzhen University, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"software","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"}]},{"given":"Xiaofang","family":"Pan","sequence":"additional","affiliation":[{"name":"College of Electronics and Information Engineering, Shenzhen University, Shenzhen 518060, China"},{"name":"National Key Laboratory of RF Heterogeneous Integration, Shenzhen University, Shenzhen 518060, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"funding-acquisition","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"7476","DOI":"10.1016\/j.atmosenv.2008.05.066","article-title":"Hydrogen Sulfide (H2S) in Urban Ambient Air","volume":"42","author":"Kourtidis","year":"2008","journal-title":"Atmos.
