   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.

   Participation in the technical sessions provided the opportunity to attend multiple oral presentations focused on recent advances in artificial olfaction systems. These presentations covered topics such as sensor array optimization, temperature modulation techniques, and embedded implementations, among others. Additionally, several discussions addressed the current limitations of electronic nose and electronic tongue technologies, including sensor selectivity, long-term stability, repeatability, environmental sensitivity, and challenges associated with calibration and real-world deployment. These sessions contributed to a broader understanding of current research trends and future directions in the field.

   During the poster sessions, the research work entitled “Temperature-Modulated Electronic Nose Using Digital Gas Sensors” was presented to conference participants. The poster presentation enabled detailed technical discussions with researchers and attendees regarding the system architecture, experimental methodology, signal processing strategies, feature extraction techniques, and experimental results. Furthermore, the feedback received during these interactions provided valuable insights into potential improvements, future research directions, and possible application scenarios for the proposed system.

   In addition to the scientific sessions, participation in the Sniffest competition represented a significant practical component of the conference activities. In collaboration with another researcher, an electronic nose system designed for the discrimination of Chinese medicinal herbs was developed and presented. The system employed gas sensor array measurements combined with pattern recognition techniques to identify characteristic volatile compound profiles associated with different herbal samples. The competition involved comparative evaluation against systems developed by other international research groups, considering criteria such as classification accuracy, response speed, and overall system performance. The proposed electronic nose achieved third place in the competition, demonstrating the effectiveness of the implemented sensing and classification methodology and providing external validation of the system’s capabilities.

   Overall, attendance at ISOEN 2026 provided valuable exposure to current state-of-the-art developments in electronic nose and electronic tongue technologies, facilitated technical exchange with international researchers, and contributed to the dissemination and validation of the presented research within the scientific community specializing in artificial olfaction and chemical sensing systems.
