We built a tiny electronic nose that can beat a mouse at its own game

Imagine a robot that can detect scents in the air and track down their sources as efficiently as a dog or a mouse. By constantly measuring and re-adjusting the temperature with a high level of precision, we achieved a highly sensitive sensor response that could detect even slight, fast changes in odors. Drones equipped with fast electronic noses could change that by patrolling the forests, identifying small plumes of smoke, then navigating towards and localizing the source. Olfactory robots equipped with fast electronic noses could play a life-saving role by detecting the unique scent signatures of humans trapped under debris. By rapidly scanning through complex environments and identifying human scent traces, these robots could guide rescue teams to victims faster than traditional methods, increasing the chances of survival.
