Researchers have developed a new, safe, and painless noninvasive method to enhance the sense of smell using radiofrequency (RF) stimulation targeted at the olfactory nerves near the forehead.

Initial results showed that participants experienced significant improvements in their ability to detect odors, with effects lasting around one week.

The study involved volunteers with normal olfactory function, and improvements were measured through odor detection tests and brain signal recordings.

This innovative technique offers a promising alternative to current treatments for smell loss, which are often limited, invasive, or less effective.

The approach aims to directly stimulate the olfactory system, which is notoriously difficult to access due to its deep location inside the head.

While initial testing was on individuals with normal smell, researchers believe this method could benefit professionals like perfumers, chefs, and coffee tasters, and may help those with smell impairments such as anosmia or hyposmia in future studies.

Future research plans include extending the study to individuals with olfactory dysfunction to assess its potential as a therapeutic treatment for those most in need.
