Scentronic: An artificial intelligence-assisted olfactory interface for remote odor sharing and transmission.

An IoT-enabled olfactory interface with AI-assisted sensing and wearable actuation demonstrates scalable remote odor sharing and multisensory stimulation.

• Why it matters: Olfaction is vital for perception, memory, and emotion, yet current systems struggle to accurately capture, transmit, and reproduce odors, limiting applications in medical and immersive experiences.
• What they did: The authors designed, characterized, and applied an integrated framework combining AI-assisted odor sensing with a wearable piezoelectric olfactory actuation system, including device, circuit, and software components.
• The result: This work establishes a scalable platform for IoT-based olfactory interaction, enabling remote odor sensing, stimulation, and multisensory experiences that advance human-machine interfaces toward incorporating chemical senses.
