On December 3, 2025, Prof. Kong Jie from Northwestern Polytechnical University and Prof. Wu Weiwei from Xidian University were invited to visit the Institute of New Concept Sensors and Molecular Materials at Shaanxi Normal University, and give reports titled “Polymer-Converted Absorbing Materials: From Precursors to Metamaterials” and “DDisease Volatilomics and Electronic Nose Diagnostics” respectively.

Prof. Kong Jie presented the latest research findings on polymer-based absorptive materials, covering material design, synthesis, and their applications in electromagnetic wave absorption. He emphasized the significance of metamaterials in modern technology and shared his team’s recent advancements and future research directions in this field.

Prof. Wu Weiwei began by explaining the working principles of electronic noses and the methodology behind breath diagnosis research. He then detailed his team’s preliminary work addressing bottlenecks in artificial olfactory receptors for electronic noses, including developments in conductive polymer VOC sensor arrays, methods for suppressing humidity interference in sensors, passive VOC sensor arrays using polymer composite films, and clinical urine odor detection for bladder cancer, as well as the team’s efforts in electronic nose system design and manufacturing.

The sessions were chaired by INCSMM vice dean Prof. Ding Liping, and attended by nearly 80 participants, including Prof. Liu Feng from Xi’an Jiaotong University and faculty members and students from the institute.
