Created by Susanna Hertrich, Jacobson’s Fabulous Olfactometer (JFO) is a sensorial prosthesis that mimics mammalian ‘flehmen’ when air pollution levels are high. The prosthetic is designed around a new human sense modeled after a mammalian sense organ called the vomeronasal or “Jacobson’s” organ. This olfactory sense organ enables certain animals to sense odourless chemicals. When a mammal senses chemicals, it lifts its upper lip to expose this organ. This behaviour is called ‘flehmen’ (wikipedia).
