Essence: Olfactory Interfaces for Unconscious Influence of Mood and Cognitive Performance
summary
A wearable olfactory necklace that Bluetooth-controls scent bursts claims to nudge mood and memory by varying intensity and timing based on context and physiology. It uses a piezoelectric droplet generator, a 7 ml cartridge (about 28 hours at a 1s/20s duty cycle), and integrates Muse EEG and heart‑rate inputs plus a stretch trigger. A four‑participant, three‑day pilot reports comfortable long‑term wear and usable control, while limitations include tiny sample size, single‑cartridge capacity, and a bulky electronics pack.
