Methane (CH₄) is a strong greenhouse gas and dangerous in industrial settings, so highly sensitive and reliable sensors are needed to detect it at low concentrations. In this study, ZnO-based thick-film gas sensors were fabricated using a screen-printing technique on Kapton substrates and evaluated for methane sensing at room temperature. The device consists of an interdigitated electrode (IDE) and a ZnO sensing layer, both deposited onto the Kapton substrate via screen printing. The prepared sensors were then tested with methane at 6700 ppm and 7500 ppm concentrations. Results show that both ZnO sensors have good linearity in I-V measurements meaning that they exhibit ohmic behavior. ZnO2 sensitivity was higher than ZnO1 probably due to some microstructural differences. Resistance changes during gas exposure were used as the sensor response
