Imagine smelling freshly brewed coffee through a video call or getting a whiff of perfume before buying it online. Scientists are bringing that idea closer to reality with Scentronic, an AI-powered system that can detect smells, transmit scent data over the Internet, and recreate aromas remotely. Scentronic works a little like a digital nose paired with a tiny perfume dispenser. Its electronic nose uses six gas sensors to detect chemical compounds associated with an aroma. AI then identifies the smell and transmits the relevant data to a receiving device, which recreates it using scented liquids and miniature vibrating atomizers that release tiny droplets into the air. The prototype currently supports five aromas: coffee, beer, red wine, cake, and orange. It doesn’t transmit actual odor molecules across the Internet. Instead, it identifies a scent and recreates an approximation using ingredients already loaded into the receiving device. Researchers see potential applications in online shopping, digital communication, and virtual reality. Imagine exploring a virtual bakery and smelling freshly baked cake, or testing a fragrance remotely before spending money on a bottle. Of course, there’s a catch. Scentronic can’t reproduce every smell on demand, and its current capabilities depend on the aromas its ingredients can recreate. Still, the research suggests that digital experiences could eventually engage more than just our eyes and ears.
