Abstract
This study focuses on developing homemade inks in order to prepare inkjet-printed gas sensor on a flexible substrate. The primary challenge lies in formulating metallic inks with long term stability, high concentration, and inkjet compatible properties. Two distinct methodologies were explored: one cen-tered around nanoparticle-based synthesis, while the other one was particle-free. To achieve an opera-tional sensor, numerous layers were deposited, ranging from gold electrodes to platinum resistance and a SnO₂ sensing layer. Every stage of the manufacturing process has been optimized, allowing to obtain a functional device.
