Tongue

Spanish researchers have developed an electronic tongue capable of distinguishing between different varieties of cava wine based on how much sugar was added during production.

Spanish researchers have developed an "electronic tongue" for analyzing the content of antioxidant powders, along with fruit and fruit products.

A student at Tokyo's University of Electro-Communications has invented a robotic tongue device for online kissing.

A new device aims to help restore the experience of vision for the blind and visually impaired by using nerves on the tongue's surface to send light signals to the brain.

Invented by European scientists, this handheld device has a multi-sensor chip which senses distinctive characteristics of wine varieties. By analyzing the sugar content, acidity and alcohol, the machine can also determine the year and grape variety of the sample.
