The technology can transport small droplets of flavor to a person's tongue using acoustic waves

Researchers at the University of Sussex have developed a method to transport small amounts flavor to a person’s taste buds through acoustic waves. This was done through an ultrasonic transducer that produces the waves. The different flavors demanded a unique acoustic energy to carry it to the person’s tongue, however, so it was important to ensure that once it arrive to the person the flavor had not changed.

The researchers at Sussex collaborated with a team from the University of Bristol in a study that brought a series of participants in to test how well they could detect three flavors: sweet, bitter and umami (also known as savory). Sweet and umami were the easiest to detect, whereas bitter was the hardest for participants to point out. This technology could prove useful in various mediums outside of a creative kitchen, such as providing depth to a virtual reality game.

While the researchers have completed a prototype, they hope to add more sophisticated flavors that would allow a person taste a full meal without having to eat one. As of right now, they can combine certain flavors together, like coffee, water and milk.
