Scentronic: Advancement in odor transmission over the internet

Human-machine interface (HMI) technology has advanced rapidly, but olfaction, a fundamental chemical sense, still faces challenges. Capturing, transmitting, and reproducing odors accurately is complicated, and there is a lack of standardized and network-enabled platforms. A recent study presents an Internet of Things (IoT)-enabled olfactory interface capable of sensing and stimulating odors remotely. The system combines an artificial intelligence-assisted odor sensing platform with a portable piezoelectric olfactory activation device. The researchers demonstrated the design, characterization, and application of this framework, which integrates devices, circuit architecture, and software algorithms ¹.

Applications and potentials

The technology can be used in medical contexts, such as psychophysical tests to study olfactory pathways and assess sensory loss. Furthermore, the integration of olfactory and gustatory interfaces promises enhanced sensory immersion. The system, named Scentronic, can already transmit odors of orange, beer, and cake, among others. The creators hope to expand the capacity to include more aromas, such as the scent of a pine forest or the aroma of coffee. This could enrich virtual worlds and remote communication, adding a new sensory dimension ².
