Olfaction feedback systems are valuable for stimulating emotions, increasing alertness, providing clinical therapy, and creating immersive virtual environments. Current technologies face challenges including perceivable odor manipulation delays, bulky sizes, and limited odor supplies. This research presents a wearable, high-performance olfactory interface using miniaturized odor generators (OGs) and advanced AI algorithms. The OGs achieve millisecond response times, milliwatt power consumption, and miniaturized size. Empowered by AI, the interface enables latency-free mixed reality (MR) and fast olfaction enhancement, bridging electronics and users for diverse applications.
