Abstract: Modern gas-monitoring requirements for numerous demanding applications ranging from medical diagnostics, to environmental surveillance, and to residential/industrial safety push the limits of existing detection concepts to the point where we may reach their fundamental performance limits. Thus, without violating the laws of physics, chemistry, and electronics and without crossing the border into the 21st century science fantasy, we need to develop new analytical concepts and instruments. This talk will stimulate your scientific and engineering senses by (1) posing several fundamental and practical questions on principles of gas sensing and (2) demonstrating on how modern multidisciplinary research addresses these questions in the developments of sensors with previously unthinkable capabilities. We will discuss new sensor-design criteria that allow multi-gas detection with individual sensors and the key roles of advanced sensing materials, transducers, and data analytics to achieve desired sensor performance. These developed multi-gas sensors are attractive when selectivity advantages of classic analytical instruments are cancelled by requirements for no consumables, low power, low cost, and unobtrusive form factors. We will conclude with a perspective for future needs in fundamental and applied aspects of gas sensing and with the 2025 roadmaps for ubiquitous gas monitoring.
