A low cost printed, AI-programmable, multi-gas sensor based on biodegradable nanomaterials.

Printable ink-based materials react to various gases, producing resistance changes. Various inks react in different ways to different gases. By having two or more different ink-based sensing elements it is possible to identify specific gases by looking at the resistances of various ink-based sensing elements. The combination acts like a fingerprint, which is unique for each gas. This multi-channel reaction is used as training data for AI, which then interprets the measurement result as presence and concentration of existing gas(es) in a continuous measurement.
