Ultrasound Device Brings Scent to Virtual Reality Without Chemicals
5 articles · Updated · UploadVR · Apr 15
Researchers have developed a device that induces the sensation of smell using focused ultrasound, eliminating the need for chemical cartridges.
The device targets the olfactory bulb through the forehead, allowing users to experience smells like fresh air, garbage, ozone, and campfire.
This approach could revolutionize virtual reality by enabling immersive scent experiences and may have broader implications for non-invasive brain-computer interfaces.

Breakthrough in Real-Time Scent Technology Enhances Immersive VR Experiences
Overview
In February 2026, researchers from the Institute of Science Tokyo and Rakuten Mobile announced a breakthrough wearable olfactory display that overcomes previous limitations like bulkiness and slow response by using multi-channel design, ultrasonic atomization, and electroosmotic pumps. This device enhances virtual reality by seamlessly adding realistic scents, significantly increasing user immersion and presence. It opens new possibilities in entertainment, training, therapy, and product demonstrations. While user testing confirms its impact, challenges remain with scent persistence, allergy risks, hygiene for shared use, and limited scent complexity. Ongoing prototype refinements aim to address these issues ahead of a planned commercial rollout in 2027-2028, positioning the technology for entry into the rapidly growing VR market.
