Gas sensing is becoming critical for applications ranging from gas speciation of indoor and outdoor air-quality  to monitoring of energy-assets, precision agriculture, noninvasive medical diagnostics, and security. However, conventional legacy gas sensors rely on single-output designs that struggle with drift and detection of low-concentration analytes in chemically complex environments. In this lecture we will present a roadmap toward next-generation multi-output gas sensors: inspired by proven traditional analytical instruments such as gas chromatography and spectroscopy, we will show how their underlying mathematical principles can be translated into new sensing designs to improve selectivity, stability, and reliability. The central focus of this lecture is understanding of importance of hardware–analytics co-design. Machine learning (ML) cannot fully succeed when sensor outputs contain insufficient independent information. Thus, emerging multi-output sensor architectures - enabled by independent excitation variables, advances in electronics, and edge analytics - create the information richness needed for multi-analyte discrimination, drift correction, and robust calibration. Using multiple examples from research teams worldwide, we will connect foundational principles to practical design strategies and illustrate commercialization pathways. We will provide a systems-level understanding of how to design multi-output gas sensors to achieve trusted performance in chemically complex environments.
