- Researchers developed an ultrasound device that induces smell by targeting the olfactory bulb in the brain, bypassing the nose.
- This approach avoids issues of previous smell technologies, which relied on chemical cartridges and faced legal and practical limitations.
- The device uses low-frequency ultrasound focused through the forehead, with specific parameters like 300 kHz and 39 mm depth.
- It can produce smells like fresh air, garbage, ozone, and campfire, described as either strong localized smells or diffuse sensations.
- Potential applications extend beyond VR to non-invasive brain-computer interfaces, though commercialization for consumers remains distant.
