Abstract
In this work, the response of SnO₂ gas sensing layers manufactured via spark-ablated nanoparticleimpaction printing, spray pyrolysis, and sputter coating is tested for acetone, NH₃, and CO₂. The spark-ablation-based layers show a higher response to all test gases. This is due to the high surface-area-to-volume ratio ofnanoporous layers, a morphology inherent to spark ablation-made layers. Dry-printing layers via spark ablation isan attractive technique for responsive SnO₂ gas sensors, fabricated in one step without the need for solvents orcomplicated post-processing. These benefits can help drive innovation in gas sensing layers.
