The dream of many – to try the taste through a monitor – is getting closer. A team of biomedical engineers and virtual reality experts has developed a groundbreaking lollipop-shaped interface that simulates taste in virtual reality. Their research, published in the Proceedings of the National Academy of Sciences, represents a significant step toward integrating the senses of taste and smell into virtual environments—an area that has long lagged behind visual and auditory advancements. The device, resembling a lollipop, uses an innovative system involving agar-agar gel infused with various chemical flavors. When a small voltage of 2V is applied, the transparent, seaweed-derived gel is pushed to the surface. There, it mixes with saliva to create a convincing taste sensation.

The intensity of each flavor is adjustable by varying the voltage, and combinations of these ingredients can generate entirely new taste experiences. Initial tests confirm the device’s effectiveness, though current limitations include the gel’s quantity, which allows for about an hour of use per device. This prototype, while promising, is just the beginning. The engineers aim to expand its capabilities, potentially integrating up to 100 flavors and extending the device’s lifespan in future iterations. Beyond its entertainment potential, the lollipop interface has practical applications. For instance, it could revolutionize online marketing by enabling consumers to “taste” products virtually before purchasing. In medicine, doctors could use it to test the palatability of medications for patients. Additionally, it could serve as an educational tool in interactive games designed for children with eating disorders. As virtual reality technologies continue to evolve, devices like this bring us closer to fully immersive experiences, blending sight, sound, and now taste into the digital realm.
