High-Performance SnO2 Ink for Detecting Low-Temperature H2S Gas with Advanced Dispensing Printing Technology

Hydrogen sulfide (H2S) is a highly toxic and environmentally hazardous gas, necessitating sensitive and reliable detection at trace concentrations. In this study, a dispensing-printed SnO2-based MEMS gas sensor was developed using a sol–gel-derived SnO2 precursor ink deposited di...
