Imagine tasting the taste of the cake without a single bite. Scientists have developed a groundbreaking device that tastes in virtual reality, explaining how we experience digital interactions. Ohio State University’s innovative ‘e-swak’ interface designed by researchers, using sensors and chemical dispenser enables remote tastes to see tastes. This advancement not only enhances VR experiences, but can also pave the way for new applications in gaming, healthcare and accessibility.

The ‘e-waste’ interface sensor and wireless chemical dispenser appoints to enable remote taste perception, also known as gustation. Field tests conducted by researchers at Ohio State University confirmed the ability to digitally simulate a series of taste intensity while maintaining diversity and safety for the user. These sensors are calibrated to separate glucose and glutamate molecules, which represents five basic tastes: sweet, sour, salty, bitter and umami. Once collected through electrical signals, the data is transmitted to a distant device for wirelessly replication.
Jinghua Lee, the co-writer of the study and assistant professor of material science and engineering in Ohio State, said, “The chemical dimension in the current VR and AR sector is relatively low, especially when we talk about olfactory and hemishes,” said Jinghua Li, “the co-writer of the study and assistant professor of material science and engineering in the Ohio State. “This is a difference that needs to be filled, and we have developed it with the next generation system.”
The system, which was inspired by the development of Lee’s previous biosensor work, uses an actuator with two parts: an interface for the mouth and a small electromagnetic pump. This pump connects a liquid channel of chemicals, which passes through an electric charge, when pushing the solution through a special gel layer in the mouth of the subject through a special gel layer.
Based on the length of this time that the solution interacts with this gel layer, the intensity and strength of any given taste can be easily adjusted, Lee said.
“Depending on the digital instructions, you can also choose to release one or several different tastes simultaneously so that they can create different sensations,” he said.
The study was published in Journal Science Advance today.

Taste is a subjective meaning that can change from one moment to another. Nevertheless, this complex spirit is the product of two of the chemical sensing systems of the body that what you eat is safe and nutritious: to ensure the gustation and olfactory (or odor) senses.
“Taste and smell are very related to human emotion and memory,” Lee said. “So our sensor will have to learn to catch, control and store all that information.”
Despite the difficulty involved in mimicking the same taste sensations for most people, researchers found that in human tests, the participating can distinguish with an accuracy rate of about 70%between various citrus intensity in the fluids generated by the system.
Further tests that assessing the ability of e-sure to immerse the players in a virtual food experience also analyzed its long distance abilities, showing that the remote tasting could be started from a distance as California in Ohio. Another experiment included subjects that were trying to identify the five food options they believed, whether it was lemonade, cake, fried egg, fish soup, or coffee.
Although these results open opportunities to pursue new VR experiences, the findings of this team are particularly important because they can potentially provide scientists with more intimate understanding of how the brain processes sensory signals from the mouth, Lee said.
The plan to increase technology rotates to further shorten the system and improve the compatibility of the system with various chemical compounds in food producing taste sensations. Beyond helping to create a better and more dynamic gaming experience, the study notes that work can be useful for persons with disabilities to reach virtual places and promote inclusion, such as painful brain injuries or long covids, which attract mainstance attention.
“This will help people join in virtual spaces,” Lee said. “This concept is here, and it is a good first step to become a small part of metavors.”
