Olfactory art is a form of artistic expression that uses scent as its primary medium. Artists create experiences that engage the sense of smell, often incorporating various fragrances, essential oils, or even natural materials. This type of art challenges traditional visual and auditory forms, inviting audiences to explore emotions and memories through scent. Exhibitions of olfactory art may include installations, performances, or interactive pieces where viewers can smell and interact with the artwork. Notable figures in this field include Sissel Tolaas, who explores the relationship between scent and memory, and Cecilia Vicuña, who incorporates olfactory elements into her installations.
