New York, March 2 (NationPress) Researchers have created an innovative technology aimed at transforming the virtual reality landscape by adding a new sensory dimension – taste.
This interface, known as ‘e-Taste’, integrates a series of sensors and wireless chemical dispensers to enable the remote experience of taste, a process termed gustation.
The sensors are designed to detect molecules such as glucose and glutamate — compounds that signify the five fundamental tastes: sweet, sour, salty, bitter, and umami.
Captured through an electrical signal, this data is transmitted wirelessly to a distant device for replication, as explained by researchers from Ohio State University in the United States.
“The chemical aspect of current VR and AR technologies is notably lacking, particularly regarding olfaction and gustation,” stated Jinghua Li, the study's co-author and an assistant professor of materials science and engineering at Ohio State.
“This is a gap that we have addressed with this cutting-edge system,” added Li.
The system's development was influenced by earlier biosensor research conducted by Li and features an actuator composed of two components: an interface for the mouth and a compact electromagnetic pump.
This pump is linked to a liquid channel of chemicals that vibrates upon receiving an electric charge, propelling the solution through a unique gel layer into the participant's mouth.
According to Li, the interaction duration of the solution with the gel layer can be adjusted to modify the intensity and strength of a specific taste.
“Based on digital commands, you can opt to release one or multiple tastes simultaneously to create various sensations,” she mentioned. The findings were published in the journal Science Advances.
Additional tests evaluating the e-Taste’s capacity to immerse users in a virtual culinary experience also examined its long-range functionality, revealing that remote tasting could be initiated in Ohio from as far away as California.
One experiment involved participants attempting to identify five food options they sensed, including lemonade, cake, fried egg, fish soup, or coffee.
“While these findings pave the way for pioneering new VR experiences, they are particularly important as they may offer scientists a deeper insight into how the brain interprets sensory signals from the mouth,” highlighted Li.
