Tongue

For those unfortunate enough to suffer from severe spinal cord injuries, the tongue is often the only extremity still under their control. To take advantage of this fact, engineers at the Georgia Institute of Technology have developed what they call the Tongue Drive System (TDS), a wireless, wearable device that allows the user to operate computers and control electric wheelchairs with movements of the tongue. The latest iteration, which resembles a sensor-studded dental retainer, is controlled by a tongue-mounted magnet and promises its users a welcome new level of autonomy with both communication and transportation.  Read More

Spanish efforts to find an electronic alternative to the tried and tested expertise of a human sommelier have now resulted in a system that can tell the difference between varieties of sparkling wine. The new development combines advanced mathematical processing tools with chemical measurement systems and an artificial neural network to create an electronic tongue currently capable of identifying the characteristics of just three cava wines, but with the potential to learn all types available on the market.  Read More

Not to be confused with the bizarre robotic tongue prototype, “electronic tongues” have been in use for the past several years, for assessing the content of various foods and beverages – and no, unfortunately they don’t look like actual tongues. While past examples have been used for purposes such as identifying the vintage and grape variety of wines, researchers from Spain’s Universitat Politècnica de València (UPV) have recently developed one that analyzes the content of antioxidant powder, along with fruit and fruit products.  Read More

Services such as Skype have certainly made things a little easier for geographically-separated romantic partners, but when the tele-chat is over and it's time to say good night, sometimes a little air kiss blown towards a webcam just isn't enough. While there are products that cater for the long-distance physical needs of couples, those might be a bit much for everyday situations. There's also the KissPhone, which attempts to simulate the sensation of one partner's lips against the other's. Sitting between those two extremes, however, is the "Kiss Transmission Device" – a prototype gizmo designed to allow its users to virtually lock tongues.  Read More

According to the National Institutes of Health, more than one million Americans over the age of 40 are legally blind - defined by U.S. law as vision that is 20/200 or worse, or have a field of view that is less than 20 degrees in diameter. It is estimated that adult vision loss costs the country about $51.4 billion per year. 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.  Read More

Could this new electronic wine-tasting tongue challenge the finest wine tasters in the world? 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 and instead of waiting days for laboratories to analyze wine samples, wine industry specialists will be able to get a sample result at the touch of a button.  Read More
