ISOEN 2026 was held from May 17 to 20, 2026, in Chongqing. This international conference is one of the main scientific forums dedicated to research and technological development in the fields of artificial olfaction, gas sensing systems, electronic noses, and electronic tongues. The event brought together researchers, industry representatives, and academic institutions working on sensor technologies, signal processing, pattern recognition, and analytical instrumentation for chemical sensing applications.

   The conference program included a wide range of scientific and technical activities, such as specialized tutorials, oral technical sessions, poster presentations, and technology-oriented competitions.

   After a series or many meetings during the first months of the year, the IEEE working group developing the IEEE P2520.1 draft has reached its final stage of development, bringing the baseline standard for machine olfaction devices and systems closer to completion. This draft defines a common testing framework for these devices, with the goal of measuring their performance in differentiation, recognition, and quantification tasks.

   The new IEEE standard P2520.1 is designed to provide a baseline performance standard that can be applied across a wide range of machine olfaction technologies. The document makes clear that it is intended as a foundation for the broader P2520 series, allowing more application-specific standards to build on top of a shared testing structure. Mr. James Covington, convenor of this initiative, recently talked about this new standard in the 24h-MOM.
